2009-06-22s3: forward MSG_DEBUG from smbd parent to all childrenAravind Srinivasan1-0/+19
Before 3.3, an smbcontrol debug message sent to the target "smbd" would actually be sent to all running processes including nmbd and winbindd. This behavior was changed in 3.3 so that the "smbd" target would only send a message to the process found in smbd.pid, while the "all" target would send a message to all processes. The ability to set the debug level of all processes within a single daemon, without specifying each pid is quite useful. This was implemented in winbindd in 065760ed. This patch does the same thing for smbd. Upon receiving a MSG_DEBUG the parent smbd will rebroadcast it to all of its children. The printing process has been added to the list of smbd child processes, and we now always track the number of smbd children regardless of the "max smbd processes" setting.

2009-06-10s3: Prepare the first set of SMB_VFS_CREATE_FILE callers to take an ↵Tim Prouty1-53/+95
smb_filename struct Some of the callers required minimal changes, while others (copy_internals) required significant changes. The task is simplified a little bit because we are able to do operations and checks on the base_name when a stream isn't used. This patch should cause no functional changes.

2009-06-10s3: Remove extraneous calls to unix_convertTim Prouty1-6/+0
Not only are these unnecessary in spirit because unlink_internals calls unix_convert, but in practice the return value is simply being ignored right now.
2009-05-27s3: Allow child processes to exit gracefully if we are out of fdsMarc VanHeyningen2-4/+5
When we run out of file descriptors for some reason, every new connection forks a child that immediately panics causing smbd to coredump. This seems unnecessarily harsh; with this code change we now catch that error and merely log a message about it and exit without the core dump. Signed-off-by: Tim Prouty <tprouty@samba.org>
2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke3-4/+4
This patch introduces struct stat_ex { dev_t st_ex_dev; ino_t st_ex_ino; mode_t st_ex_mode; nlink_t st_ex_nlink; uid_t st_ex_uid; gid_t st_ex_gid; dev_t st_ex_rdev; off_t st_ex_size; struct timespec st_ex_atime; struct timespec st_ex_mtime; struct timespec st_ex_ctime; struct timespec st_ex_btime; /* birthtime */ blksize_t st_ex_blksize; blkcnt_t st_ex_blocks; }; typedef struct stat_ex SMB_STRUCT_STAT; It is really large because due to the friendly libc headers playing macro tricks with fields like st_ino, so I renamed them to st_ex_xxx. Why this change? To support birthtime, we already have quite a few #ifdef's at places where it does not really belong. With a stat struct that we control, we can consolidate the nanosecond timestamps and the birthtime deep in the VFS stat calls. At this moment it is triggered by a request to support the birthtime field for GPFS. GPFS does not extend the system level struct stat, but instead has a separate call that gets us the additional information beyond posix. Without being able to do that within the VFS stat calls, that support would have to be scattered around the main smbd code. It will very likely break all the onefs modules, but I think the changes will be reasonably easy to do.
2009-05-20s3: Change unix_convert (and its callers) to use struct smb_filenameTim Prouty1-1/+16
This is the first of a series of patches that change path based operations to operate on a struct smb_filename instead of a char *. This same concept already exists in source4. My goals for this series of patches are to eventually: 1) Solve the stream vs. posix filename that contains a colon ambiguity that currently exists. 2) Make unix_convert the only function that parses the stream name. 3) Clean up the unix_convert API. 4) Change all path based vfs operation to take a struct smb_filename. 5) Make is_ntfs_stream_name() a constant operation that can simply check the state of struct smb_filename rather than re-parse the filename. 6) Eliminate the need for split_ntfs_stream_name() to exist. My strategy is to start from the inside at unix_convert() and work my way out through the vfs layer, call by call. This first patch does just that, by changing unix_convert and all of its callers to operate on struct smb_filename. Since this is such a large change, I plan on pushing the patches in phases, where each phase keeps full compatibility and passes make test. The API of unix_convert has been simplified from: NTSTATUS unix_convert(TALLOC_CTX *ctx, connection_struct *conn, const char *orig_path, bool allow_wcard_last_component, char **pp_conv_path, char **pp_saved_last_component, SMB_STRUCT_STAT *pst) to: NTSTATUS unix_convert(TALLOC_CTX *ctx, connection_struct *conn, const char *orig_path, struct smb_filename *smb_fname, uint32_t ucf_flags) Currently the smb_filename struct looks like: struct smb_filename { char *base_name; char *stream_name; char *original_lcomp; SMB_STRUCT_STAT st; }; One key point here is the decision to break up the base_name and stream_name. I have introduced a helper function called get_full_smb_filename() that takes an smb_filename struct and allocates the full_name. I changed the callers of unix_convert() to subsequently call get_full_smb_filename() for the time being, but I plan to eventually eliminate get_full_smb_filename().

2009-05-12s3-printing: Fix vlp testprinter application.Günther Deschner1-24/+23
Jeremy, we cannot just access cache_path() here without calling lp_load and friends as well as parsing configfile from the commandline in order to make "make test/selftest" find the correct conffile with path, etc. I just changed it to pass the target tdbfilename as an argument, ok ? Guenther
2009-05-11Hopefully fix the buildfarm. Add some debug level 10 messagesJeremy Allison2-5/+20
I used to track down the vlp problem, change the vlp test printer not to use a static path of /tmp/vlp.tdb for the virtual print database (as this will eventually fill up). Cause it to use a virtual print database inside the cachepath. Jeremy.

2009-03-01Only copy sharename up from rap_to_pjobidVolker Lendecke2-3/+4
Why?? :-) Another one of the little micro-optimizations that I just came across: If you allocate a variable in a sub-block like the "fstring sharename" in write_file(), gcc even with -O3 will allocate this variable unconditionally on the stack at the beginning of the routine. So with eliminating this fstring we cut 256 bytes of stack in a very hot code path writing to a file. It might make us a bit more cache-friendly. This would probably not be worth a second look if it involved larger code changes, but this one was just too simple to let it pass :-)

2009-02-24s3-spoolss: fix notify_printer_status_byname.Günther Deschner1-1/+3
This took me almost a week to find, so here a little longer explanation: When a windows client registers printer *status* change notifies using spoolss_RemoteFindFirstChangeNotify, it registers them to a print server handle, not a printer handle. We were then correctly monitoring the printer status changes but were sending out the spoolss_RouterReplyPrinterEx via the back-channel connection with job_id set to 0 (which we only may do for monitored printer change status notifies on printer handlers, not print server handles). Windows was then showing a new empty dummy printer icon in the explorer as it cannot route the notify event to the approriate local handle. It also discarded the content of the notify event message of course. With this, printer change notify for pausing, resuming and purging printers nicely works again here. Jerry, Tim and all other printing gurus, please check. Guenther
