2018-06-19sys/epoll.h: add EPOLLNVAL from linux v4.16Szabolcs Nagy-0/+1
added to uapi in commit 65aaf87b3aa2d049c6b9fd85221858a895df3393 used since commit a9a08845e9acbd224e4ee466f5c1275ed50054e8, which renamed POLL* to EPOLL* in the kernel.
2016-03-19add EPOLLEXCLUSIVE epoll flag from linux v4.5Szabolcs Nagy-0/+1
new flag for exclusive wakeup mode when an event source fd is attached to multiple epoll fds but they should not all receive the events. new in linux commit df0108c5da561c66c333bb46bfe3c1fc65905898
2013-03-06fix epoll structure alignment on non-x86_64 archsRich Felker-1/+5
this fix is far from ideal and breaks the rule of not using arch-specific #ifdefs, but for now we just need a solution to the existing breakage. the underlying problem is that the kernel folks made a very stupid decision to make misalignment of this struct part of the kernel API/ABI for x86_64, in order to avoid writing a few extra lines of code to handle both 32- and 64-bit userspace on 64-bit kernels. I had just added the packed attribute unconditionally thinking it was harmless on 32-bit archs, but non-x86 32-bit archs have 8-byte alignment on 64-bit types.

2012-12-27align EPOLL_* flags with fcntl O_* flag definitions, which vary by archRich Felker-2/+3
the old definitions were wrong on some archs. actually, EPOLL_NONBLOCK probably should not even be defined; it is not accepted by the kernel and it's not clear to me whether it has any use at all, even if it did work. this issue should be revisited at some point, but I'm leaving it in place for now in case some applications reference it.
