* Use our own variant of 'assert' and 'assert_perror'.Justus Winter2017-08-051-23/+23
| | | | | Our variants print stack traces on failures. This will make locating errors much easier.
* ext2fs: Do not talk about crashing on ENOSPCSamuel Thibault2016-11-201-1/+1
| | | | | * ext2fs/pager.c (pager_unlock_page): Do not say that ext2fs will crash because of ENOSPC.

| | | | | | | | | | | | | | | | | | | | | Add a variant to 'pager_create' that allocates memory for the user hook next to the pager data increasing locality. * console/pager.c (pager_clear_user_data): Fix type of 'idx', do not free 'upi'.

* ext2fs: fix pager use-after-freeJustus Winter2016-05-221-11/+20
| | | | | | | | | | | | | Previously, pagers had no reference for being part of a node, only for having a send right made for them. Hence we sometimes saw use-after-free errors if the kernel did give up that send right, typically while deleting files. Keep a weak reference as long as the pager is referenced by a node. * ext2fs/pager.c (pager_clear_user_data): Assert that 'pager' has been NULLed. (pager_dropweak): Drop the weak reference and NULL 'pager'. (diskfs_get_filemap): Simplify. Acquire a weak reference.

| | | | | | | | | * ext2fs/pager.c (disk_cache_info_free_push): Add prototype. (disk_pager_notify_evict): When dropping DC_INCORE flag, if the block becomes free (no reference and no DC_DONT_REUSE flags), call disk_cache_info_free_push. (disk_cache_block_deref): Only call disk_cache_info_free_push if the flags of the block do not contain DC_DONT_REUSE flags.

* Fix race condition in ext2fs when remountingJames Clarke2015-09-061-1/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On some systems, ext2fs.static would regularly hang at startup, as a race condition meant it would process paging requests while remounting. To fix this, libpager has been altered to allow inhibiting and resuming its worker threads, and ext2fs uses this to inhibit paging while remounting. * console/pager.c (pager_requests): New variable. (user_pager_init): Updated call to pager_start_workers to use new pager_requests variable. * daemons/runsystem.sh: Removed artificial delay working around the race condition. * ext2fs/ext2fs.c (diskfs_reload_global_state): Call new inhibit_ext2_pager and resume_ext2_pager functions, and leave sblock as non-NULL so it will be munmapped. * ext2fs/ext2fs.h (inhibit_ext2_pager,resume_ext2_pager): New functions. * ext2fs/pager.c (file_pager_requests): New variable.

Replaced queue with queue_in and queue_out pointers. Added inhibit_wakeup field. (pager_demuxer): Updated to use new queue_in/queue_out pointers. Only wake up workers if not inhibited. (worker_func): Updated to use new queue_in/queue_out pointers. Final worker thread to sleep notifies the inhibit_wakeup condition variable. (pager_start_workers): Added out parameter for the requests instance. Allocate heap space shared by both queues. Initialise new inhibit_wakeup condition.

* libpager: use a fixed number of threadsJustus Winter2014-11-031-25/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, libpager used an unbounded number of threads to receive messages from the pager bucket. It used sequence barriers to execute the requests to order requests to each object. The sequence barriers are implemented in seqnos.c. A server function uses _pager_wait_for_seqno to wait for its sequence number and _pager_release_seqno to release it, or it uses _pager_update_seqno to do both operations in one step. These sequence barriers divide each server function in three parts: A, B, and C. A_i happens "before" the sequence barrier i, B_i happens "in order", C_i happens "after" the sequence barrier. This partial order < has the following properties: * This order is *per object*. Requests to different objects are not ordered. * A_i < B_i, B_i < C_i (due to the structure of the code) * B_i < B_{i+1} (this is due to the sequence barriers) * Note that only the B parts are ordered by the sequence numbers, we are free to execute C_i and C_{i+1} in any possible order. The same argument applies to the A parts. The sequence barriers are implemented using a very simple ticket algorithm. Every request, even the invalid ones, is processed by a thread, and waits until the ticket count reaches its seqno, does some work in-order, then increments the ticket and awakes all threads that have piled up up to this moment. All of them except one will then discover that it's not their turn yet and go to sleep again. Creating one thread per request has proven to be problematic as memory_object requests often arrive in large batches. This patch does two things: * Use a single thread to receive messages from the port bucket. All incoming request are put into a queue. * Use a fixed-number of threads (though even one is actually enough) to execute the the server functions. If multiple threads are used, a work-delegation mechanism ensures that the per object order < is preserved. For reference, I used the following command to create workloads that highlight the problem this patch is addressing: % settrans t .../ext2fs --sync=30 /dev/sd2s1 ... % /usr/bin/time zsh -c 'for ((i=0; i < 1500; i++)); do dd if=/dev/zero of=t/src/$i bs=4k count=290 2>/dev/null echo -n . if ((i % 100 == 0)) ; then echo -n $i; fi done' * libpager/queue.h: New file. * libpager/demuxer.c: Manage a queue of requests received from the port bucket.

* ext2fs: use two distinct pager buckets for the disk and file pagerJustus Winter2014-05-051-25/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | ext2fs has two kinds of pagers. One for the files, one for the disk. Previously, both were in the same port bucket. If a request for a file pager arrives, it most likely touches some metadata (like the superblock). This is in turn backed by the disk pager, so another request is generated for the disk pager. Seperate all pagers clearly by using two port buckets. This will enable us to use a single thread per port bucket in the future. * ext2fs/pager.c (pager_bucket): Rename to... (disk_pager_bucket): ... this to make the change explicit at every occurrence. (file_pager_bucket): New variable. (service_paging_requests): New function.

* Sync pager before clearing MAY_CACHE flagSergio López2011-10-031-1/+4
| | | | | | | | | | | | | | | Clearing MAY_CACHE flag on a pager initiates a memory object termination if this one is not referenced anymore. If the object has a significant number of dirty pages (i.e. a file recently created was unlinked before diskfs periodical sync) this operation generates a lot of stress on the translator. This is one of the most common sources for thread storms. Sync'ing the pager before clearing that flag ensures that there aren't dirty pages in the object before its termination. * ext2fs/pager.c (drop_pager_softrefs): Sync pager before clearing MAY_CACHE flag.
