fdget(), more trivial conversions

2024-11-03T06:28:06Z

all failure exits prior to fdget() leave the scope, all matching fdput() are immediately followed by leaving the scope. [xfs_ioc_commit_range() chunk moved here as well] Reviewed-by: Christian Brauner Signed-off-by: Al Viro

introduce fd_file(), convert all accessors to it.

2024-08-13T02:00:43Z

For any changes of struct fd representation we need to turn existing accesses to fields into calls of wrappers. Accesses to struct fd::flags are very few (3 in linux/file.h, 1 in net/socket.c, 3 in fs/overlayfs/file.c and 3 more in explicit initializers). Those can be dealt with in the commit converting to new layout; accesses to struct fd::file are too many for that. This commit converts (almost) all of f.file to fd_file(f). It's not entirely mechanical ('file' is used as a member name more than just in struct fd) and it does not even attempt to distinguish the uses in pointer context from those in boolean context; the latter will be eventually turned into a separate helper (fd_empty()). NOTE: mass conversion to fd_empty(), tempting as it might be, is a bad idea; better do that piecewise in commit that convert from fdget...() to CLASS(...). [conflicts in fs/fhandle.c, kernel/bpf/syscall.c, mm/memcontrol.c caught by git; fs/stat.c one got caught by git grep] [fs/xattr.c conflict] Reviewed-by: Christian Brauner Signed-off-by: Al Viro

net: change proto and proto_ops accept type

2024-05-14T00:19:09Z

Rather than pass in flags, error pointer, and whether this is a kernel invocation or not, add a struct proto_accept_arg struct as the argument. This then holds all of these arguments, and prepares accept for being able to pass back more information. No functional changes in this patch. Acked-by: Jakub Kicinski Signed-off-by: Jens Axboe

ocfs2: cluster: fix potential deadlock on &o2net_debug_lock

2023-08-18T17:18:59Z

&o2net_debug_lock is acquired by timer o2net_idle_timer() along the following call chain. Thus the acquisition of the lock under process context should disable bottom half, otherwise deadlock could happen if the timer happens to preempt the execution while the lock is held in process context on the same CPU. -> o2net_idle_timer() -> queue_delayed_work() -> sc_put() -> sc_kref_release() -> o2net_debug_del_sc() -> spin_lock(&o2net_debug_lock); Several lock acquisition of &o2net_debug_lock under process context do not disable irq or bottom half. The patch fixes these potential deadlocks scenerio by using spin_lock_bh() on &o2net_debug_lock. This flaw was found by an experimental static analysis tool I am developing for irq-related deadlock. x86_64 allmodconfig using gcc shows no new warning.
