2024-06-21monitor: Report errors from monitor_fdset_dup_fd_addFabiano Rosas
I'm keeping the EACCES because callers expect to be able to look at errno. Reviewed-by: Peter Xu <peterx@redhat.com> Signed-off-by: Fabiano Rosas <farosas@suse.de>
2024-06-20monitor: Drop monitor_fdset_dup_fd_find/_remove()Peter Xu
Those functions are not needed, one remove function should already work. Clean it up. Here the code doesn't really care about whether we need to keep that dupfd around if close() failed: when that happens something got very wrong, keeping the dup_fd around the fdsets may not help that situation so far.

2024-04-18stubs: move monitor_fdsets_cleanup with other fdset stubsPaolo Bonzini
Even though monitor_get_fd() has to remain separate because it is mocked by tests/unit/test-util-sockets, monitor_fdsets_cleanup() is logically part of the stubs for monitor/fds.c, so move it there.

2020-09-16monitor: simplify functions for getting a dup'd fdset entryDaniel P. Berrangé
Currently code has to call monitor_fdset_get_fd, then dup the return fd, and then add the duplicate FD back into the fdset. This dance is overly verbose for the caller and introduces extra failure modes which can be avoided by folding all the logic into monitor_fdset_dup_fd_add and removing monitor_fdset_get_fd entirely.

2019-06-17monitor: Fix return type of monitor_fdset_dup_fd_findYury Kotov
monitor_fdset_dup_fd_find_remove() and monitor_fdset_dup_fd_find() return mon_fdset->id which is int64_t. Downcasting from int64_t to int leads to a bug with removing fd from fdset with id >= 2^32. So, fix return types for these function.

2018-06-18monitor: add lock to protect mon_fdsetsPeter Xu
Introduce a new global big lock for mon_fdsets. Take it where needed. The monitor_fdset_get_fd() handling is a bit tricky: now we need to call qemu_mutex_unlock() which might pollute errno, so we need to make sure the correct errno be passed up to the callers. To make things simpler, we let monitor_fdset_get_fd() return the -errno directly when error happens, then in qemu_open() we move it back into errno.
