* multiple xlators: reduce key lengthYaniv Kaul2020-01-1417-125/+123
| | | | | | | | | | | | | | | In many cases, we were freely allocating long keys with no need. Smaller char arrays are just fine almost anywhere, so just went ahead and looked where they we can use smaller ones. In some cases, annotated the functions as static and the prefixes passed as const as it was easier to read and understand. Where relevant, converted the dict functions to use known key length.

* dict: use the free_pair's key presence or NULL as a sign of use.Yaniv Kaul2020-01-132-18/+15
| | | | | | | | | | | | | Instead of using a boolean parameter, we can use the key variable. If it's NULL, the pair is not used and can be used. Otherwise, it's in use - don't use. It saves this annoying boolean, which causes the compiler (or us explicitly) to pad with additional bytes the dict struct.

Strangely, I could not reproduce the failure on my system (Fedora 31), but it was reproduced elsehwere and the fix was verified to correct it. The failure: gluster volume create testvol replica 3 127.0.0.2:/tests/brick{1..3} force gluster v set testvol write-behind off grep -rne write-behind /var/lib/glusterd/vols/testvol/trusted-testvol.tcp-fuse.vol The last grep was supposed to come out empty.

* multiple: fix bad type castXavi Hernandez2020-01-106-21/+42
| | | | | | | | | | | | When using inode_ctx_get() or inode_ctx_set(), a 'uint64_t *' is expected. In many cases, the value to retrieve or store is a pointer, which will be of smaller size in some architectures (for example 32-bits). In this case, directly passing the address of the pointer casted to an 'uint64_t *' is wrong and can cause memory corruption.

* fuse: degrade logging of write failure to fuse deviceCsaba Henk2020-01-092-7/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: FUSE uses failures of communicating with /dev/fuse with various errnos to indicate in-kernel conditions to userspace. Some of these shouldn't be handled as an application error. Also the standard POSIX errno description should not be shown as they are misleading in this context. Solution: When writing to the fuse device, the caller of the respective convenience routine can mask those errnos which don't qualify to be an error for the application in that context, so then those shall be reported at DEBUG level. The possible non-standard errnos are reported with their POSIX name instead of their description to avoid confusion. (Eg. for ENOENT we don't log "no such file or directory", we log indeed literal "ENOENT".)

| | | | | | | | | | | | | | | All the structs present inside xlators/features/leases have been re-aligned into memory efficient way. Changes are made in such a way that every members are 8 byte aligned and no padding is left out in the 8 byte line. Manual padding has been added to remove compile time padding (which happens at the end of the struct). This manual padding is for development and debugging benefits. It lets to use -Wpadded option and raise warnings from the remaining structs where compile time padding happens.

The phenomenon is as follows. ------------------------------------------------------------------------------ NFS Server on localhost 2049 0 N 48406 Quota Daemon on localhost N/A N/A N 48428 ------------------------------------------------------------------------------ Solution: The cause of the above phenomenon is that the log path of valgrind is set incorrectly.

There are many changes coming in gcc-10 described in https://gcc.gnu.org/gcc-10/changes.html compiling cli.c with gcc-9 we see: ... .quad .LC88 .comm cli_ten_minutes_timeout,4,4 .comm cli_default_conn_timeout,4,4 .text .Letext0: ... and with gcc-10: ... .quad .LC88 .globl cli_ten_minutes_timeout .bss .align 4 .type cli_ten_minutes_timeout, @object .size cli_ten_minutes_timeout, 4 cli_ten_minutes_timeout: .zero 4 .globl cli_default_conn_timeout .align 4 .type cli_default_conn_timeout, @object .size cli_default_conn_timeout, 4 cli_default_conn_timeout: .zero 4 .text .Letext0: ... which is reflected in the .o file as (gcc-9): ... 0000000000000004 C cli_ten_minutes_timeout 0000000000000004 C cli_default_conn_timeout ... and (gcc-10): ... 0000000000000020 B cli_ten_minutes_timeout 0000000000000024 B cli_default_conn_timeout ... See nm(1) and ld(1) for a description C (common) and B (BSS) and how they are treated by the linker. Note: there is still a small chance that gcc-10 will land in Fedora-32, despite 31 Dec. 2019 having been the deadline for that to happen.

* Avoid buffer overwrite due to uuid_utoa() misuseDmitry Antipov2019-12-275-25/+40
| | | | | | | | | | | | | | | Code like: f(..., uuid_utoa(x), uuid_utoa(y)); is not valid (causes undefined behaviour) because uuid_utoa() uses the only static thread-local buffer which will be overwritten by the subsequent call. All such cases should be converted to use uuid_utoa_r() with explicitly specified buffer.

* timer: fix event destruction raceXavi Hernandez2019-12-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In current timer implementation, each event has an absolute time at which it will be fired. When the first timer of the queue has not elapsed yet, a pthread_cond_timedwait() is used to wait until the expected time. Apparently that's fine. However the time passed to that function was a pointer to the timespec structure contained in the event itself. This is problematic because of how pthread_cond_timedwait() works internally. Simplifying a bit, pthread_cond_timedwait() basically queues itself as a waiter for the given condition variable and releases the mutex. Then it does the timed wait using the passed value. With that in mind, the follwing case is possible: Timer Thread Other Thread ------------ ------------ gf_timer_call_cancel() pthread_mutex_lock() | + pthread_mutex_lock() event = current_event() | pthread_cond_timedwait(&event->at) | + pthread_mutex_unlock() | | + remove_event() | + destroy_event() + timed_wait(&event->at) As we can see, the time is used after it has been destroyed, which means we have a use-after-free problem. This patch fixes the problem by copying the time to a local variable before calling pthread_cond_timedwait() Change-Id: I0f4e8eded24fe3a1276dc75c6cf093bae973d26b Signed-off-by: Xavi Hernandez <xhernandez@redhat.com> Fixes: bz#1785208
* Revert "store.c: remove a sys_stat() call - just open the file"Sanju Rakonde2019-12-251-1/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit da735ad9b58b76d27c580a9feb63f14b2cc0669d. This commit is changing the behaviour of glusterd during its initialization. The removed piece of code checks whether the file mentioned in the path exists or not, if not it returns -1. This return value is considered for the sub sequent operations. By removing this code, we always return 0 and some part of the code will not be executed in the following code path. glusterd_options_init() -> glusterd_store_retrieve_options() -> gf_store_handle_retrieve() In glusterd_options_init(), we are not executing any code if the ret value is 0. ret = glusterd_store_retrieve_options(this); if (ret == 0) { goto out; } as we are not executing any code if the return value is 0, we are unable to enable the brick-multiplex feature using volume set. fixes: bz#1786459 Change-Id: I4f52b7b2ea8adb8df5087bb96927e9bb7db5b491

* tests/fuse/bug-965974.t: turn off md-cache, to fix failure of the testRaghavendra G2019-12-191-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Imagine the following set of operations: 1. touch $M0/file 2. ln $M0/file $M0/file.lnk 3. rm $M1/file 4. wait for md-cache-timeout 5. stat $M0/file.lnk $M0/file stat on $M0/file in step 5 succeeds when md-cache-timeout is non-zero even though it was removed from $M1. The reason is 1. fuse-bridge on $M0 would resolve both file and file.lnk to same inode. This inode i1 is cached in md-cache. 2. After md-cache-timeout lookup on $M0/file.lnk would be sent to backend. This lookup will be successful as file.lnk is present on backend and would refresh the md-cache. 3. The lookup on $M0/file sent within md-cache-timeout after lookup on $M0/file.lnk would be sent with i1. Since i1 was refreshed by lookup on $M0/file.lnk, the cache is deemed valid and md-cache responds lookup on $M0/file as success To fix this failure we can either: 1. remove lookup on $M0/file.lnk, so that lookup on $M0/file is actually sent to backend. 2. turn off md-cache This patch chooses option 2. credits: Csaba Henk <csaba@redhat.com> Change-Id: I352c2acd377fe10c4bdf3b6e53c1de86a4e544c7 Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Updates: bz#1756900
