paths - -The current epoll code can be tickled to run basically indefinitely in -both loop detection path check (on ep_insert()), and in the wakeup paths. -The programs that tickle this behavior set up deeply linked networks of -epoll file descriptors that cause the epoll algorithms to traverse them -indefinitely. A couple of these sample programs have been previously -posted in this thread: https://lkml.org/lkml/2011/2/25/297. - -To fix the loop detection path check algorithms, I simply keep track of -the epoll nodes that have been already visited. Thus, the loop detection -becomes proportional to the number of epoll file descriptor and links. -This dramatically decreases the run-time of the loop check algorithm. In -one diabolical case I tried it reduced the run-time from 15 mintues (all -in kernel time) to .3 seconds. - -Fixing the wakeup paths could be done at wakeup time in a similar manner -by keeping track of nodes that have already been visited, but the -complexity is harder, since there can be multiple wakeups on different -cpus...Thus, I've opted to limit the number of possible wakeup paths when -the paths are created. - -This is accomplished, by noting that the end file descriptor points that -are found during the loop detection pass (from the newly added link), are -actually the sources for wakeup events. I keep a list of these file -descriptors and limit the number and length of these paths that emanate -from these 'source file descriptors'. In the current implemetation I -allow 1000 paths of length 1, 500 of length 2, 100 of length 3, 50 of -length 4 and 10 of length 5. Note that it is sufficient to check the -'source file descriptors' reachable from the newly added link, since no -other 'source file descriptors' will have newly added links. This allows -us to check only the wakeup paths that may have gotten too long, and not -re-check all possible wakeup paths on the system. - -In terms of the path limit selection, I think its first worth noting that -the most common case for epoll, is probably the model where you have 1 -epoll file descriptor that is monitoring n number of 'source file -descriptors'. In this case, each 'source file descriptor' has a 1 path of -length 1. Thus, I believe that the limits I'm proposing are quite -reasonable and in fact may be too generous. Thus, I'm hoping that the -proposed limits will not prevent any workloads that currently work to -fail. - -In terms of locking, I have extended the use of the 'epmutex' to all -epoll_ctl add and remove operations. Currently its only used in a subset -of the add paths. I need to hold the epmutex, so that we can correctly -traverse a coherent graph, to check the number of paths. I believe that -this additional locking is probably ok, since its in the setup/teardown -paths, and doesn't affect the running paths, but it certainly is going to -add some extra overhead. Also, worth noting is that the epmuex was -recently added to the ep_ctl add operations in the initial path loop -detection code using the argument that it was not on a critical path. - -Another thing to note here, is the length of epoll chains that is allowed. -Currently, eventpoll.c defines: - -/* Maximum number of nesting allowed inside epoll sets */ -#define EP_MAX_NESTS 4 - -This basically means that I am limited to a graph depth of 5 (EP_MAX_NESTS -+ 1). However, this limit is currently only enforced during the loop -check detection code, and only when the epoll file descriptors are added -in a certain order. Thus, this limit is currently easily bypassed. The -newly added check for wakeup paths, stricly limits the wakeup paths to a -length of 5, regardless of the order in which ep's are linked together. -Thus, a side-effect of the new code is a more consistent enforcement of -the graph depth. - -Thus far, I've tested this, using the sample programs previously -mentioned, which now either return quickly or return -EINVAL. I've also -testing using the piptest.c epoll tester, which showed no difference in -performance. I've also created a number of different epoll networks and -tested that they behave as expectded. - -I believe this solves the original diabolical test cases, while still -preserving the sane epoll nesting. - -Signed-off-by: Jason Baron <jbaron@redhat.com> -Cc: Nelson Elhage <nelhage@ksplice.com> -Cc: Davide Libenzi <davidel@xmailserver.org> -Signed-off-by: Andrew Morton <akpm@linux-foundation.org> ---- - fs/eventpoll.c | 226 ++++++++++++++++++++++++++++++++++++++++----- - include/linux/eventpoll.h | 1 + - include/linux/fs.h | 1 + - 3 files changed, 203 insertions(+), 25 deletions(-) - -diff --git a/fs/eventpoll.c b/fs/eventpoll.c -index b84fad9..414ac74 100644 ---- a/fs/eventpoll.c -+++ b/fs/eventpoll.c -@@ -197,6 +197,12 @@ struct eventpoll { - - /* The user that created the eventpoll descriptor */ - struct user_struct *user; -+ -+ struct file *file; -+ -+ /* used to optimize loop detection check */ -+ int visited; -+ struct list_head visitedllink; - }; - - /* Wait structure used by the poll hooks */ -@@ -255,6 +261,12 @@ static struct kmem_cache *epi_cache __read_mostly; - /* Slab cache used to allocate "struct eppoll_entry" */ - static struct kmem_cache *pwq_cache __read_mostly; - -+/* Visited nodes during ep_loop_check(), so we can unset them when we finish */ -+LIST_HEAD(visited_list); -+ -+/* Files with newly added links, which need a limit on emanating paths */ -+LIST_HEAD(tfile_check_list); -+ - #ifdef CONFIG_SYSCTL - - #include <linux/sysctl.h> -@@ -276,6 +288,12 @@ ctl_table epoll_table[] = { - }; - #endif /* CONFIG_SYSCTL */ - -+static const struct file_operations eventpoll_fops; -+ -+static inline int is_file_epoll(struct file *f) -+{ -+ return f->f_op == &eventpoll_fops; -+} - - /* Setup the structure that is used as key for the RB tree */ - static inline void ep_set_ffd(struct epoll_filefd *ffd, -@@ -711,12 +729,6 @@ static const struct file_operations eventpoll_fops = { - .llseek = noop_llseek, - }; - --/* Fast test to see if the file is an eventpoll file */ --static inline int is_file_epoll(struct file *f) --{ -- return f->f_op == &eventpoll_fops; --} -- - /* - * This is called from eventpoll_release() to unlink files from the eventpoll - * interface.
