* s3:smbprofile: Replace sysv shmem with tdbVolker Lendecke2015-03-061-80/+301
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | What? This patch gets rid of the central shared memory segment referenced by "profile_p". Instead, every smbd gets a static profile_area where it collects profiling data. Once a second, every smbd writes this profiling data into a record of its own in a "smbprofile.tdb". smbstatus -P does a tdb_traverse on this database and sums up what it finds. Why? At least in my perception sysv IPC has not the best reputation on earth. The code before this patch uses shmat(). Samba ages ago has developed a good abstraction of shared memory: It's called tdb. The main reason why I started this is that I have a request to become more flexible with profiling data. Samba should be able to collect data per share or per user, something which is almost impossible to do with a fixed structure. My idea is to for example install a profile area per share and every second marshall this into one tdb record indexed by share name. smbstatus -P would then also collect the data and either aggregate them or put them into individual per-share statistics. This flexibility in the data model is not really possible with one fixed structure. But isn't it slow? Well, I don't think so. I can't really prove it, but I do believe that on large boxes atomically incrementing a shared memory value for every SMB does show up due to NUMA effects. With this patch the hot code path is completely process-local. Once a second every smbd writes into a central tdb, this of course does atomic operations. But it's once a second, not on every SMB2 read. There's two places where I would like to improve things: With the current code all smbds wake up once a second. With 10,000 potentially idle smbds this will become noticable. That's why the current only starts the timer when something has changed. The second place is the tdb traverse: Right now traverse is blocking in the sense that when it has to switch hash chains it will block. With mutexes, this means a syscall. I have a traverse light in mind that works as follows: It assumes a locked hash chain and then walks the complete chain in one run without unlocking in between. This way the caller can do nonblocking locks in the first round and only do blocking locks in a second round. Also, a lot of syscall overhead will vanish. This way smbstatus -P will have almost zero impact on normal operations.

* s3:smbprofile: rewrite the internal macrosStefan Metzmacher2014-11-191-188/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We now autogenerate a lot of code using SMBPROFILE_STATS_ALL_SECTIONS macro which expands to different SMBPROFILE_STATS_{COUNT,BASIC,BYTES,IOBYTES} macros. This also allows async profiling using: struct mystate { ... SMBPROFILE_BASIC_ASYNC_STATE(profile_state); ... }; ... SMBPROFILE_BASIC_ASYNC_START(SMB2_negotiate, profile_p, mystate->profile_state); ... SMBPROFILE_BYTES_ASYNC_SET_IDLE(mystate->profile_state); ... SMBPROFILE_BYTES_ASYNC_SET_BUSY(mystate->profile_state); ... SMBPROFILE_BASIC_ASYNC_END(mystate->profile_state); The current START_PROFILE*()/END_PROFILE*() are implemented as legacy wrappers.

* Rename vfs operation posix_fallocate to just fallocate and add the ↵Jeremy Allison2010-12-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | vfs_fallocate_mode parameter. It turns out we need the fallocate operations to be able to both allocate and extend filesize, and to allocate and not extend filesize, and posix_fallocate can only do the former. So by defining the vfs op as posix_fallocate we lose the opportunity to use any underlying syscalls (like Linux fallocate) that can do the latter as well. We don't currently use the non-extending filesize call, but now I've changed the vfs op definition we can in the future. For the moment simply map the fallocate op onto posix_fallocate for the VFS_FALLOCATE_EXTEND_SIZE case and return ENOSYS for the VFS_FALLOCATE_KEEP_SIZE case. Jeremy.

| | | | | | | | | | | | | | | this can only be done via fset_nt_acl() using an open file/directory handle. I'd like to do the same with get_nt_acl() but am concerned about efficiency problems with "hide unreadable/hide unwritable" when doing a directory listing (this would mean opening every file in the dir on list). Moving closer to rationalizing the ACL model and maybe moving the POSIX calls into a posix_acl VFS module rather than having them as first class citizens of the VFS. Jeremy.

A prerequisite to implement a tiny samba4-API compatible wrapper around our messaging system. That itself is necessary for the Samba4 notify system. Yes, I know, I could import the whole Samba4 messaging system, but I want to do it step by step and I think getting notify in is more important in this step.
