2009-05-27s3: Allow child processes to exit gracefully if we are out of fdsMarc VanHeyningen1-2/+3
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>
2009-05-24Fix a race condition in winbind leading to a panicVolker Lendecke1-0/+1
In winbind, we do multiple events in one select round. This needs fixing, but as long as we're still using it, for efficiency reasons we need to do that. What can happen is the following: We have outgoing data pending for a client, thus state->fd_event.flags == EVENT_FD_WRITE Now a new client comes in, we go through the list of clients to find an idle one. The detection for idle clients in remove_idle_client does not take the pending data into account. We close the socket that has pending outgoing data, the accept(2) one syscall later gives us the same socket. In new_connection(), we do a setup_async_read, setting up a read fde. The select from before however had found the socket (that we had already closed!!) to be writable. In rw_callback we only want to see a readable flag, and we panic in the SMB_ASSERT(flags == EVENT_FD_READ). Found using bin/smbtorture //127.0.0.1/tmp -U% -N 500 -o 2 local-wbclient Volker

* Adds wbcGetSidAliases that calls the lookup_useraliases function. * Updates wbinfo and winbind_util.c to call the new function. * Also added winbind_get_groups helper function.
2009-02-11s3: Implement wbcGetpwsidDan Sledz1-0/+1
* Adds the plumbing required to lookup users by sid into winbind, wbinfo and smbd helper lib (winbind_util.c). * Removes some double declarations of winbind_util.c functions. * Bumps the winbind protocol version to 21 and the minor version of wbclient to 3.

2009-01-15s3: make better use of ccache by not including version.h in every C-file.Michael Adam1-1/+1
version.h changes rather frequently. Since it is included via includes.h, this means each C file will be a cache miss. This applies to the following situations: * When building a new package with a new Samba version * building in a git branch after calling mkversion.sh after a new commit (i.e. virtually always) This patch improves the situation in the following way: * remove inlude "version.h" from includes.h * Use samba_version_string() instead of SAMBA_VERSION_STRING in files that use no other macro from version.h instead of SAMBA_VERSION_STRING. * explicitly include "version.h" in those files that use more macros from "version.h" than just SAMBA_VERSION_STRING.

2008-11-18Added ability to remove id mappings in wbinfo and libwbclient.Steven Danneman1-0/+1
The idmap_tdb backend already provides an interface to remove existing id mappings. This commit plumbs that ability up through, winbindd, libwbclient, and wbinfo. Added new winbindd command: WINBINDD_REMOVE_MAPPING Added new libwbclient interfaces: wbcRemoveUidMapping() and wbcRemoveGidMapping() Added new wbinfo options: --remove-uid-mapping --remove-gid-mapping Increased libwbclient version to 0.2 Increased winbind interface version to 20

2008-10-27[s3]winbind: fix smbd hanging on Solaris when winbindd closes socket.Michael Adam1-1/+6
On some versions of Solaris, we observed a strange effect of close(2) on a socket: After the server (here winbindd) called close, the client fd was not marked as readable for select. And a write call to the fd did not produce an error EPIPE but just returned as if successful. So while winbindd had called remove_client(), the corresponding smbd still thought that it was connected, but failed to retrieve answers for its queries. This patch works around the problem by forcing the client fd to the readable state: Just write one byte into the socket before closing. Michael

2008-07-01MSG_DEBUG now forwarded to all the winbindd children by parent.Darshan Purandare1-0/+5
smbcontrol winbindd debug level would only set the debug level of the parent winbindd process and not the child processes. This patch adds the functionality of broadcasting the debug message to all winbindd children. Now the debug level message is propagated to all the winbindd processes that includes parent and children. (This used to be commit cfbcfc3ffe74f28ec874a6bf1ab93f55f405b6e6)

2008-04-23Fix CLEAR_IF_FIRST handling of messages.tdbVolker Lendecke1-1/+1

2008-04-10winbindd: only call winbindd_validate_cache when not in offline logon mode.Michael Adam1-20/+3
originally, the cache was cleared before calling validate, but this way, we skipt the validation of the database when not in offline logon mode. This is put into a new wrapper function winbindd_cache_validate_and_initialize() which is now called in winbindd.c instead calling validate and initialize functions separately.
