* tests/features/ssl-authz.t: Fix spurious failuresEmmanuel Dreyfus2015-02-181-2/+9
| | | | | | | | | | | | | | | | | | | | Fix two spurious failures in tests/features/ssl-authz.t 1) Wait for bricks to come online after starting a volume, so that the mount is usable without "socket not connected" error 2) For a mount that must fail, we may get the situation where there is no mount at all, which means creating a file will write to the mount point instead of failing. To cover that case, write the file and check it is absent from the brick.

* glupy: portability fixesEmmanuel Dreyfus2014-11-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fixes portability problems so that NetBSD passes tests/features/glupy.t - Use python-config to detect python build environment on all systems, not just Linux and Darwin. - Get the site-package directory from python and make sure we install glupy.py there, Previously we installed within glusterfs prefix, which caused a problem if it was different that python's prefix. - Set PYTHONPATH for tests so that the detected site-packages is used in python's search path. This should be useless, but let us have it just in case. - Pass glupy.so path from glusterfsd to glupy.py through an environment variable and use it in CDLL instead of "", as the later seems not portable (at least it fails on NetBSD). - Use gil_init_key pthread_getspecific to avoid deadlocks (that code was #ifdef out, perhaps because it was not needed on Linux, but it seems to be required for NetBSD. - Recover the error message from Python and send it to the logs to help debugging problems. Backport of: http://review.gluster.org/8978 This is the same patchset as previously submitted to retrigger regression tests after a spurious failure.

* socket: disallow CBC cipher modesJeff Darcy2014-10-291-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | This is related to CVE-2014-3566 a.k.a. POODLE. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-3566 POODLE is specific to CBC cipher modes in SSLv3. Because there is no way to prevent SSLv3 fallback on a system with an unpatched version of OpenSSL, users of such systems can only be protected by disallowing CBC modes. The default cipher-mode specification in our code has been changed accordingly. Users can still set their own cipher modes if they wish. To support them, the ssl-authz.t test script provides an example of how to combine the CBC exclusion with other criteria in a script.

* Use sane OS-dependent defaults for SSL configurationEmmanuel Dreyfus2014-09-261-2/+8

* dht: support heterogeneous brick sizesJeff Darcy2014-07-121-0/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Calculation of layouts now considers the size of each brick, so that smaller bricks don't get an "unfair" share of allocations and start returning ENOSPC while the larger bricks still have plenty of space. The observation has been made that some clients might get ENOTCONN when trying to fetch disk-size information, and end up calculating layouts differently. The following meta-observations can be made. (1) This scenario is extremely unlikely in configurations with AFR. (2) The most likely consequence of this scenario is that some files will be placed sub-optimally by the client with the obsolete (non-weighted) layout. They'll still be found anyway, so this isn't a show stopper. (3) Without this patch it's *guaranteed* that some files will be placed sub-optimally, because any layout that fails to account for brick sizes is sub-optimal. (4) We shouldn't be doing fix-layout from two nodes simultaneously anyway. That's inefficient at best. Any instances of such behavior are separate bugs, which should be fixed separately. (5) In the most extreme edge case, two nodes doing weighted and non-weighted layout fixes could race and end up creating an internally inconsistent layout. This condition is still transient; it will be detected and repaired automatically the next time anyone fetches the layout. (If it's not that's also a preexisting bug that can show up in other contexts.) In conclusion, it's not the purpose of this patch to fix bugs elsewhere in DHT. Its purpose is to make life incrementally better for users who add new hardware with larger disks etc. than the older equipment. It's only one part of an ongoing process to improve layout management and repair, all the way up to support for multiple hash rings or tiering.

| | | | | | | | | | | | | | | | | | | Access to a volume is now controlled by the following options, based on whether SSL is enabled or not. * server.ssl-allow: get identity from certificate, no password needed * auth.allow: get identity and matching password from command line It is not possible to allow both simultaneously, since the connection itself is either using SSL or it isn't.

* performance/readdir-ahead: introduce directory read-ahead translatorBrian Foster2013-09-041-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a translator to improve the performance of typical, sequential directory reads (i.e., ls). readdir-ahead begins preloading the contents of a directory on open and serves readdir requests from the preloaded content. readdir-ahead is currently implemented to only handle the single threaded directory read case. readdir-ahead is currently disabled by default. It can be enabled with the following command: gluster volume set <volname> readdir-ahead on The following are results of a getdents test on a single brick volume. Test info: - Single VM, gluster client/server. - Volume mounted with native client using --gid-timeout=2. - getdents on single directory with 100k 0-byte files. Test results: - !readdir-ahead read 3120080 bytes from offset 0 3 MiB, 4348 ops, 0:00:07.00 (416.590 KiB/sec and 594.4737 ops/sec) - readdir-ahead read 3120080 bytes from offset 0 3 MiB, 4348 ops, 0:00:03.00 (820.116 KiB/sec and 1170.3043 ops/sec) BUG: 980517 Change-Id: Ieceb9e1eb47d1d5b5af8da2bf03839537364653f Signed-off-by: Brian Foster <bfoster@redhat.com> Reviewed-on: http://review.gluster.org/4519 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Anand Avati <avati@redhat.com>
