Revision 25a3bc6bd1ca03ab504b8c55c98f8d0135644d53 authored by Al Viro on 03 December 2012, 18:15:30 UTC, committed by Linus Torvalds on 03 December 2012, 19:13:09 UTC
In commit 9d73fc2d641f ("open*(2) compat fixes (s390, arm64)") I said: > > The usual rules for open()/openat()/open_by_handle_at() are > 1) native 32bit - don't force O_LARGEFILE in flags > 2) native 64bit - force O_LARGEFILE in flags > 3) compat on 64bit host - as for native 32bit > 4) native 32bit ABI for 64bit system (mips/n32, x86/x32) - as for native 64bit > > There are only two exceptions - s390 compat has open() forcing O_LARGEFILE and > arm64 compat has open_by_handle_at() doing the same thing. The same binaries > on native host (s390/31 and arm resp.) will *not* force O_LARGEFILE, so IMO > both are emulation bugs. Three exceptions, actually - parisc open() is another case like that. Native 32bit won't force O_LARGEFILE, the same binary on parisc64 will. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
