| | | | | | | | | | | | | | | | | | | | | reduce strlen()'s strncpy may not be very efficient for short strings copied into a large buffer: If the length of src is less than n, strncpy() writes additional null bytes to dest to ensure that a total of n bytes are written. Instead, use snprintf(). Also: - save the result of strlen() and re-use it when possible. - move from strlen to SLEN (sizeof() ) for const strings. Compile-tested only!

* contrib/xxhash: update to latest xxHash (0.6.5)Yaniv Kaul2018-08-163-471/+700
| | | | | | | | | | | | | | | | | | | | | | Update to latest xxHash, which is supposed to faster with small keys. Specifically, updated to 3064d42e7d74b0921bdd1818395d9cb37bb8976a, which is a bit higher than 0.6.5. Compiled hopefully with namespace (XXH_NAMESPACE=GF_), which allows to use XXH() funcs with no fear they'll 'leak' from our library. Only compile tested! xxhsum is modified to display messages which was conflicting with regression tests (TAP harness). So modified the gfid2path_fuse.t and gfid2path_nfs.t to adhere to that. updates: bz#1193929 Signed-off-by: Yaniv Kaul <ykaul@redhat.com> Change-Id: I35cea5cc93f338c1023ac2c9bc6d7d13225a967b

Prashanth notes that unicode strings in py2 need 'u' prefix; unicode strings in py3 3.0, 3.1, and 3.2 a 'u' prefix will throw an error, but in py3 3.3+ it is legal (or just ignored). All Linux dists we care about have 3.3 or later so we can leave 'u' prefixes on unicode strings. Change-Id: I49bba2f328b0ee24b9a8115a7183be979981563e updates: #411 Signed-off-by: Kaleb S.

This patch does two things: 1) minor cleanup of configure(.ac) to explicitly use python2 2) change all the shebang lines to #!/usr/bin/python2 and add them where they were missing based on warnings emitted during rpmbuild. In a follow-up patch python2 will eventually be changed to python3. Before that python2-isms (e.g. print, string.join(), etc.) need to be converted to python3. Some of those can be rewritten in version agnostic python. E.g. print statements become print() with "from __future_ import print_function". The python 2to3 utility will be used for some of those. Also Aravinda has given guidance in the comments to the first patch for changes. updates: #411 Change-Id: I471730962b2526022115a1fc33629fb078b74338 Signed-off-by: Kaleb S.

* fuse: implement "-oauto_unmount"Csaba Henk2017-05-232-0/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | libfuse has an auto_unmount option which, if enabled, ensures that the file system is unmounted at FUSE server termination by running a separate monitor process that performs the unmount when that occurs. (This feature would probably better be called "robust auto-unmount", as FUSE servers usually do try to unmount their file systems upon termination, it's just this mechanism is not crash resilient.) This change implements that option and behavior for glusterfs. Note that "auto unmount" (robust or not) is a leaky abstraction, as the kernel cannot guarantee that at the path where the FUSE fs is mounted is actually the toplevel mount at the time of the umount(2) call, for multiple reasons, among others, see: fuse-devel: "fuse: feasible to distinguish between umount and abort?" http://fuse.996288.n3.nabble.com/fuse-feasible-to-distinguish-between-umount-and-abort-tt14358.html https://github.com/libfuse/libfuse/issues/122 Updates #153 Change-Id: Ia4432580c9fd2c156d9c73c3a44f4bfd42437599 Signed-off-by: Csaba Henk <csaba@redhat.com> Reviewed-on: https://review.gluster.org/17230 Tested-by: Amar Tumballi <amarts@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Amar Tumballi <amarts@redhat.com> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>

* contrib/timerwheel: bad 32-bit, use builtin fls(), fix copyrightKaleb S. KEITHLEY2017-05-152-71/+66
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's bad form to remove other people's copyright and license when you copy their source for your own use. Defining BITS_PER_LONG as 64 is incorrect on 32-bit platforms. The mismatch between the unsigned long of the timer and the int param to fls() means on 64-bit platforms that any bits set in the high 32-bits of the the timer are lost/ignored. gf_tw_find_last_bit() is meant to find the last bit in an array of longs. It's overkill for gluster's timerwheel where we only ever pass a single long; replacing it with a direct call to fls() which is renamed to gf_tw_fls() The timer routines are slightly modified from the kernel timer functions that first appeared circa 2.6.x in .../kernel/timer.c AFAICT. find_last_bit() comes from the (linux) kernel (.../lib/find_bit.c in 4.x kernels, .../lib/find_last_bit.c in 3.x kernels) but as noted above, it is removed with this patch. __fls() comes from the linux kernel (.../include/asm-generic/ bitops/{__fls.h,builtin-__fls.h} Restoring/updating the copyright and license to the version from the 4.x kernel find_bit.c. (timer.c does not have a license, __fls.h and builtin-__fls.h do not have a copyright or license, but the whole kernel is licensed under GPLv2 anyway.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | Simply always defining BITS_PER_LONG as 64 seems like it's almost certainly wrong on 32-bit platforms and could potentially result in incorrect results. fls and, e.g., __builtin_ffs() return the same answer for any given input, making it seem like the name fls (find last set) is a misnomer and ffs (find first set, starting from the lsb) is the more accurate name. Using __builtin_ffs() causes the compiler (in intel) to emit code with the bsf (bit scan forward) insn, which is approx 3x faster than the code in ffs(), at least on the machine I tried it on. (Even so, it takes 10M+ iterations for the speed difference to be measurable. Choosing the "faster" implementation seems like a no-brainer, even if there may not be any significant gain by doing so.)

* fuse: clean up mount flag processingCsaba Henk2017-04-274-19/+148

There is a traditional syntax for this mechanism as implemented in mount(8): one passes "-ocomma,separated,mount,options" and the individual option name strings are mapped to flag bits in mount(8). FUSE further explores this idea and typically the FUSE server command lines allow further option names to be used in the "-ooption,name,list" which are then separated from the kernel sanctioned option names (to which we'll refer as "system mount options") and are passed to a platform specific lower level fuse mount helper interface. The separation of system mount option names and FUSE specific option names is also platform specific, so the general mount interface function, which in case of glusterfs is gf_fuse_mount(), should abstract this away. Therefore we change the signature of this function from int gf_fuse_mount (const char *mountpoint, char *fsname, unsigned long mountflags, char *mnt_param, pid_t *mtab_pid, int status_fd); to int gf_fuse_mount (const char *mountpoint, char *fsname, char *mnt_param, pid_t *mtab_pid, int status_fd); and deal with flag extraction in platform specific mount code. Note that the sole purpose of the mountflags argument was to indicate read-only mounting. The other system mount option names were expected to reside in the comma-separated mnt_param string, but they were not properly processed (see the referred BUG). With the new gf_fuse_mount signature read-only mounting is to be indicated as a "ro" component in mnt_param. - For Darwin, which has a dedicated, separate gf_fuse_mount implementation, gf_fuse_mount was ignoring mountflags, so only the signature had to to be adjusted. However, as bonus, we gain read-only support for Darwin, which was missing so far, given that it was indicated via the ignored mountflags. Darwin's low level mount helper relies on the "ro" component of the option string, which agrees with the new calling convention of gf_fuse_mount. - On Linux, system mount option name handling (apart from the distinguished read-only option) used to have the inadvertent side effect of adding "nosuid,nodev" as indicated in BUG; since Ia89d975d1e27fcfa5ab2036ba546aa8fa0d2d1b0 this side effect is removed, but system mount option name handling was left broken (passing system mount options other than "ro" fails to mount). - On other platforms, system mount option name handling is broken (expect for the distinguished read-only option). As of this change, in the general (non-Darwin) implementation of gf_fuse_mount we take care of proper separation of system mount names and their conversion to mount flags. For Linux, we adopt the conversion table from FUSE upstream. For other systems we just provide a best effort to support those system mount options which are understood across all Unices (nosuid,nodev,noatime,noexec,ro). (This can be improved later to provide proper plaform support.)

However the same command executed on a FreeBSD host doesn't show all this information, even for bricks stored on a linux. Additionally, for hosts other than linux, this information is shown as 'N/A' many times. This has been fixed to show as much information as it can be retrieved from the operating system. The file contrib/mount/mntent.c has been mostly rewriten because it contained many errors that caused mount information to not be retrieved on some operating systems.

* fuse: limit fusermount fallback to EPERM casesCsaba Henk2017-01-171-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two mount mechanims for fuse: 1) Call mount(2) syscall directly -- implemented by fuse_mount_sys 2) Call out to fusermount(1) helper utilty to do the mount -- implemented by fuse_mount_fusermount [Note: both libfuse and glusterfs ships a variant of this helper utility; named, respectively, fusermount and fusermount-glusterfs. The two has diverged, and are not compatible at the moment.] The intended use of 1) is privileged mounting, ie. when root is invoking the glusterfs client. (It cannot work for non-privileged users as the kernel enforces privilege for mount(2), more precisely, caller context needs CAP_SYS_ADMIN, see capabilities(7).) The intended use of 2) is unprivileged mountig, ie. when the glusterfs client is invoked by an unprivileged user. The helper utility is a setuid binary, so it can perform mount(2) on behalf of the user. The main mount routine, gf_fuse_mount, calls fuse_mount_sys first, and if that fails, tries also with fuse_mount_fusermount. This is what we call "fusermount fallback". However, in the light of the above remarks about intended use, this logic should apply if the fuse_mount_fusermount fails because of a privilege shortage, ie. with error "Operation not permitted" (errno EPERM). So far the fallback was unconditional (masking bugs of fuser_mount_sys, as it happens in referred BUG). Now we add the "errno == EPERM" condition.

Rewrite the make rules to do what xdrgen does. Now we can get rid of xdrgen. Note 1. netbsd6's sed doesn't do -i. Why are we still running smoke tests on netbsd6 and not netbsd7? We barely support netbsd7 as it is. Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with libglusterfs? A cut-and-paste mistake? It has no references to symbols in libglusterfs. Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_ regex that matches the same lines as the _extended_ regex "/#(ifndef|define|endif)/". To match the extended regex sed needs to be run with -r on Linux; with -E on *BSD. However NetBSD's and FreeBSD's sed helpfully also provide -r for compatibility. Using a basic regex avoids having to use a kludge in order to run sed with the correct option on OS X. Note 4. Not copying the bit of xdrgen that inserts copyright/license boilerplate. AFAIK it's silly to pretend that machine generated files like these can be copyrighted or need license boilerplate. The XDR source files have their own copyright and license; and their copyrights are bound to be more up to date than old boilerplate inserted by a script. From what I've seen of other Open Source projects -- e.g. gcc and its C parser files generated by yacc and lex -- IIRC they don't bother to add copyright/license boilerplate to their generated files. It appears that it's a long-standing feature of make (SysV, BSD, gnu) for out-of-tree builds to helpfully pretend that the source files it can find in the VPATH "exist" as if they are in the $cwd. rpcgen doesn't work well in this situation and generates files with "bad" #include directives. E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`, you get an #include directive in the generated .c file like this: ... #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h" ... which (obviously) results in compile errors on out-of-tree build because the (generated) header file doesn't exist at that location. Compared to `rpcgen ./glusterfs3-xdr.x` where you get: ... #include "glusterfs3-xdr.h" ... Which is what we need. We have to resort to some Stupid Make Tricks like the addition of various .PHONY targets to work around the VPATH "help". Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/... looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | glusterfs relies on Linux uuid implementation, which API is incompatible with most other systems's uuid. As a result, libglusterfs has to embed contrib/uuid, which is the Linux implementation, on non Linux systems. This implementation is incompatible with systtem's built in, but the symbols have the same names. Usually this is not a problem because when we link with -lglusterfs, libc's symbols are trumped. However there is a problem when a program not linked with -lglusterfs will dlopen() glusterfs component. In such a case, libc's uuid implementation is already loaded in the calling program, and it will be used instead of libglusterfs's implementation, causing crashes. A possible workaround is to use pre-load libglusterfs in the calling program (using LD_PRELOAD on NetBSD for instance), but such a mechanism is not portable, nor is it flexible. A much better approach is to rename libglusterfs's uuid_* functions to gf_uuid_* to avoid any possible conflict. This is what this change attempts.

* contrib/timer-wheel: import linux kernel timer-wheelVenky Shankar2015-03-183-0/+417
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch imports timer-wheel[1] algorithm from the linux kernel (~/kernel/time/timer.c) with some modifications. Timer-wheel is an efficent way to track millions of timers for expiry. This is a variant of the simple but RAM heavy approach of having a list (timer bucket) for every future second. Timer-wheel categorizes every future second into a logarithmic array of arrays. This is done by splitting the 32 bit "timeout" value into fixed "sliced" bits, thereby each category has a fixed size array to which buckets are assigned. A classic split would be 8+6+6+6 (used in this patch) which results in 256+64+64+64 == 512 buckets. Therefore, the entire 32 bit futuristic timeouts have been mapped into 512 buckets. [ NOTE: There are other possible splits, such as "8+8+8+8", but this patch sticks to the widely used and tested default. ] Therfore, the first category "holds" timers whose expiry range is between 1..256, the next cateogry holds 257..16384, third category 16385..1048576 and so on. When timers are added, unless it's in the first category, timers with different timeouts could end up in the same bucket. This means that the timers are "partially sorted" -- sorted in their highest bits. The expiry code walks the first array of buckets and exprires any pending timers (1..256). Next, at time value 257, timers in the first bucket of the second array is "cascaded" onto the first category and timers are placed into respective buckets according to the thier timeout values. Cascading "brings down" the timers timeout to the coorect bucket of their respective category. Therefore, timers are sorted by their highest bits of the timeout value and then by the lower bits too.

* Do not use umount -l on non Linux systemsEmmanuel Dreyfus2015-01-021-2/+4
| | | | | | | | | | | | | | Lazy unmount are only supported on Linux. Force umount instead, since this code path is used in emergency exit anyway. On NetBSD, just have the filesystem calling exit, the kernel will unmount.

| | | | | | | | | | | | | | | | | | 1) Use a system-dependent macro for umount(8) location instead of relying on $PATH to find it, for security and portability sake. 2) Introduce gf_umount_lazy() to replace umount -l (-l for lazy) invocations, which is only supported on Linux; On Linux behavior in unchanged. On other systems, we fork an external process (umountd) that will take care of periodically attempt to unmount, and optionally rmdir.
