| 2008-07-23 | Correct cases of mishandling of pending reads and writes to prevent | Bob Beck | |
| them going negative - this consists of identifying a number of cases of IO not going through the buffer cache and marking those buffers with B_RAW - as well as fixing nfs_bio to show pending writes and reads through the buffer cache via NFS still has a problem with mishandling the counters I believe in the async/sync fallback case where counters stay positive which will be addressed seperately. ok tedu@ deraadt@ | |||
| 2008-06-14 | A bunch of pool_get() + bzero() -> pool_get(..., .. | PR_ZERO) | Michael Knudsen | |
| conversions that should shave a few bytes off the kernel. ok henning, krw, jsing, oga, miod, and thib (``even though i usually prefer FOO|BAR''; thanks for looking. | |||
| 2008-06-12 | Bring biomem diff back into the tree after the nfs_bio.c fix went in. | Theo de Raadt | |
| ok thib beck art | |||
| 2008-06-11 | back out biomem diff since it is not right yet. Doing very large | Theo de Raadt | |
| file copies to nfsv2 causes the system to eventually peg the console. On the console ^T indicates that the load is increasing rapidly, ddb indicates many calls to getbuf, there is some very slow nfs traffic making none (or extremely slow) progress. Eventually some machines seize up entirely. | |||
| 2008-06-10 | Fix buffer cache pending read statistics by ensuring we can identify | Bob Beck | |
| biowait() reads that do *not* come from the buffer cache - we use the B_RAW flag to identify these at art's suggestion - since it makes sense and the flag was not being used. this just flags all these buffers with B_RAW - biodone already ignores returned buffers marked B_RAW. ok art@ | |||
| 2008-06-10 | Buffer cache revamp | Bob Beck | |
| 1) remove multiple size queues, introduced as a stopgap. 2) decouple pages containing data from their mappings 3) only keep buffers mapped when they actually have to be mapped (right now, this is when buffers are B_BUSY) 4) New functions to make a buffer busy, and release the busy flag (buf_acquire and buf_release) 5) Move high/low water marks and statistics counters into a structure 6) Add a sysctl to retrieve buffer cache statistics Tested in several variants and beat upon by bob and art for a year. run accidentally on henning's nfs server for a few months... ok deraadt@, krw@, art@ - who promises to be around to deal with any fallout | |||
| 2008-06-09 | Update access(2) to have modern semantics with respect to X_OK and | Todd C. Miller | |
| the superuser. access(2) will now only indicate success for X_OK on non-directories if there is at least one execute bit set on the file. OK deraadt@ thib@ otto@ | |||
| 2008-05-08 | retire vn_default_error() and replace all instances | Thordur I. Bjornsson | |
| with eopnotsupp() instead; ok blambert@ | |||
| 2007-12-09 | update pedro's email address, at his request; | Jason McIntyre | |
| 2007-10-29 | MALLOC/FREE -> malloc/free | Charles Longeau | |
| ok krw@ | |||
| 2007-10-06 | Oops. Forgot to do FREE -> free when I did MALLOC -> malloc. | Kenneth R Westerback | |
| 2007-10-03 | MALLOC+bzero -> malloc+M_ZERO. | Kenneth R Westerback | |
| In ip_esp.c all allocated memory is now zero'd in the "malloc(sizeof(*tc) + alen ..." case. The +alen memory was not initialized by the bzero() call. Noticed by chl@. "Looks good" art@ "seems ok" chl@ | |||
| 2007-09-17 | Only the most obvious bzero() -> M_ZERO changes. No cast changes, no | Kenneth R Westerback | |
| MALLOC/FREE, etc. Just adding M_ZERO to malloc() and deleting an immediately adjacent bzero(). | |||
| 2007-06-08 | all disklabels read from the kernel now always contain a total sector | Theo de Raadt | |
| size which is the REAL DISK SIZE. always. if a driver fails to set this right, please fix it. agreed with otto and krw | |||
| 2007-06-06 | now that all partition size/offsets are potentially 64-bit, change the | Theo de Raadt | |
| type of all variables to daddr64_t. this includes the APIs for XXsize() and XXdump(), all range checks inside bio drivers, internal variables for disklabel handling, and even uvm's swap offsets. re-read numerous times by otto, miod, krw, thib to look for errors | |||
| 2007-06-05 | use six new macros to access & store the 48-bit disklabel fields related | Theo de Raadt | |
| to size. tested on almost all machines, double checked by miod and krw next comes the type handling surrounding these values | |||
| 2007-06-01 | pedro ok'd this ~3500 line diff which removes the vop argument | Theo de Raadt | |
| "ap = v" comments in under 8 seconds, so it must be ok. and it compiles too. | |||
| 2007-06-01 | FIBMAP is used by nothing; checked by miod and pvalchev | Theo de Raadt | |
| 2007-05-09 | lockmgr_printinfo() calls only if DIAGNOSTIC | Theo de Raadt | |
| 2007-04-13 | Remove cluster reading from cd9660_read(); wich doesnt work. | Thordur I. Bjornsson | |
| From mickey@; ok thib@,miod@ | |||
| 2007-04-11 | Remove the simplelock argument from vrecycle(); | Thordur I. Bjornsson | |
| ok pedro@, sturm@ | |||
| 2007-04-10 | ``it's'' -> ``its'' when the grammar gods require this change. | Miod Vallat | |
| 2007-03-25 | Remove LK_INTERLOCK from flags in a call to vget(); | Thordur I. Bjornsson | |
| ok pedro@ | |||
| 2007-03-25 | Account for the space of all the previous sessions on disk when | Pedro Martelletto | |
| mounting a multisession CD, as they may be accessed as well. From FreeBSD via Enache Adrian, okay krw@ thib@ tedu@. | |||
| 2007-03-21 | Remove the v_interlock simplelock from the vnode structure. | Thordur I. Bjornsson | |
| Zap all calls to simple_lock/unlock() on it (those calls are #defined away though). Remove the LK_INTERLOCK from the calls to vn_lock() and cleanup the filesystems wich implement VOP_LOCK(). (by remvoing the v_interlock from there calls to lockmgr()). ok pedro@, art@, tedu@ | |||
| 2007-03-21 | Add support for mounting arbitrary sessions, from Enache Adrian | Pedro Martelletto | |
| OK deraadt@ mjc@ canacar@ krw@, with much input from Enache himself | |||
| 2007-02-14 | Consistently spell FALLTHROUGH to appease lint. | Jonathan Gray | |
| ok kettenis@ cloder@ tom@ henning@ | |||
| 2007-01-16 | Retire VOP_LEASE(); It was a bit for NQNFS and has | Thordur I. Bjornsson | |
| effectively been a no-op for quite some time now, without promise for future usage. ok pedro@ Testing by krw@ (earlier diff) and Johan Mson Lindman (tybollt@solace.miun.se) | |||
| 2006-12-29 | Avoid void * arithmetic, okay deraadt@, suggestions from millert@ | Pedro Martelletto | |
| 2006-10-16 | Use daddr64_t for logical blocks, okay krw@ thib@ mickey@ | Pedro Martelletto | |
| 2006-10-03 | Introduce daddr64_t and use it for physical block numbers | Pedro Martelletto | |
| Okay weingart@, "I'm game with putting my name on it" dlg@ | |||

| 2006-08-07 | Revert last commit | Pedro Martelletto | |
| 2006-08-06 | obey the locking disaplince wrt to VOP_CLOSE during umounts | Thordur I. Bjornsson | |
