2000-06-12enable the Linux change notify code and change some notify debug codeAndrew Tridgell1-6/+17
(This used to be commit c6be511fcc1be79619a0184f03d4c33dbfe12f04)
2000-06-12totally rewrote the async signal, notification and oplock notificationAndrew Tridgell1-12/+17
handling in Samba. This was needed due to several limitations and races in the previous code - as a side effect the new code is much cleaner :) in summary: - changed sys_select() to avoid a signal/select race condition. It is a rare race but once we have signals doing notification and oplocks it is important. - changed our main processing loop to take advantage of the new sys_select semantics - split the notify code into implementaion dependent and general parts. Added the following structure that defines an implementation: struct cnotify_fns { void * (*register_notify)(connection_struct *conn, char *path, uint32 flags); BOOL (*check_notify)(connection_struct *conn, uint16 vuid, char *path, uint32 flags, void *data, time_t t); void (*remove_notify)(void *data); }; then I wrote two implementations, one using hash/poll (like our old code) and the other using the new Linux kernel change notify. It should be easy to add other change notify implementations by creating a sructure of the above type. - fixed a bug in change notify where we were returning the wrong error code. - rewrote the core change notify code to be much simpler - moved to real-time signals for leases and change notify Amazingly, it all seems to work. I was very surprised! (This used to be commit 44766c39e0027c762bee8b33b12c621c109a3267)
2000-06-11a better test for oplocks being enabled in this kernelAndrew Tridgell1-1/+18
(This used to be commit cc0e919fdcb116c8f9688a4f5d7803fc8d7f9588)
2000-06-11fixed Linux capabilities handlingAndrew Tridgell1-21/+39
I used a trick where CAP_LEASE isn't claimed until it is needed. This means we avoid a system call per setreuid(), and never call capset() unless a user tries to get a oplock on a file that they don't own (This used to be commit afa98d511f70f455d599c3a36dd25e49fe74ac09)
2000-06-11Linux kernel oplocks now seem to work, but need a _lot_ of testingAndrew Tridgell1-6/+57
I had to modify sys_select() to not loop on EINTR. I added a wrapper called sys_select_intr() which gives the old behaviour. (This used to be commit b28cc4163bc2faaa80c5782fc02c8f03c410cdeb)
2000-06-10a first pass at Linux kernel oplocks supportAndrew Tridgell1-0/+205
