2019-01-04selftests/bpf: Test [::] -> [::1] rewrite in sys_sendmsg in test_sock_addrAndrey Ignatov
Test that sys_sendmsg BPF hook doesn't break sys_sendmsg behaviour to rewrite destination IPv6 = [::] with [::1] (BSD'ism). Two test cases are added: 1) User passes dst IPv6 = [::] and BPF_CGROUP_UDP6_SENDMSG program doesn't touch it. 2) User passes dst IPv6 != [::], but BPF_CGROUP_UDP6_SENDMSG program rewrites it with [::]. In both cases [::1] is used by sys_sendmsg code eventually and datagram is sent successfully for unconnected UDP socket. Example of relevant output: Test case: sendmsg6: set dst IP = [::] (BSD'ism) .. [PASS] Test case: sendmsg6: preserve dst IP = [::] (BSD'ism) ..

2019-01-04bpf: Fix [::] -> [::1] rewrite in sys_sendmsgAndrey Ignatov
sys_sendmsg has supported unspecified destination IPv6 (wildcard) for unconnected UDP sockets since 876c7f41. When [::] is passed by user as destination, sys_sendmsg rewrites it with [::1] to be consistent with BSD (see "BSD'ism" comment in the code). This didn't work when cgroup-bpf was enabled though since the rewrite [::] -> [::1] happened before passing control to cgroup-bpf block where fl6.daddr was updated with passed by user sockaddr_in6.sin6_addr (that might or might not be changed by BPF program). That way if user passed [::] as dst IPv6 it was first rewritten with [::1] by original code from 876c7f41, but then rewritten back with [::] by cgroup-bpf block. It happened even when BPF_CGROUP_UDP6_SENDMSG program was not present (CONFIG_CGROUP_BPF=y was enough). The fix is to apply BSD'ism after cgroup-bpf block so that [::] is replaced with [::1] no matter where it came from: passed by user to sys_sendmsg or set by BPF_CGROUP_UDP6_SENDMSG program.

2019-01-04x86: re-introduce non-generic memcpy_{to,from}ioLinus Torvalds
This has been broken forever, and nobody ever really noticed because it's purely a performance issue. Long long ago, in commit 6175ddf06b61 ("x86: Clean up mem*io functions") Brian Gerst simplified the memory copies to and from iomem, since on x86, the instructions to access iomem are exactly the same as the regular instructions. That is technically true, and things worked, and nobody said anything. Besides, back then the regular memcpy was pretty simple and worked fine. Nobody noticed except for David Laight, that is. David has a testing a TLP monitor he was writing for an FPGA, and has been occasionally complaining about how memcpy_toio() writes things one byte at a time. Which is completely unacceptable from a performance standpoint, even if it happens to technically work. The reason it's writing one byte at a time is because while it's technically true that accesses to iomem are the same as accesses to regular memory on x86, the _granularity_ (and ordering) of accesses matter to iomem in ways that they don't matter to regular cached memory. In particular, when ERMS is set, we default to using "rep movsb" for larger memory copies. That is indeed perfectly fine for real memory, since the whole point is that the CPU is going to do cacheline optimizations and executes the memory copy efficiently for cached memory. With iomem? Not so much. With iomem, "rep movsb" will indeed work, but it will copy things one byte at a time. Slowly and ponderously. Now, originally, back in 2010 when commit 6175ddf06b61 was done, we didn't use ERMS, and this was much less noticeable. Our normal memcpy() was simpler in other ways too. Because in fact, it's not just about using the string instructions. Our memcpy() these days does things like "read and write overlapping values" to handle the last bytes of the copy. Again, for normal memory, overlapping accesses isn't an issue. For iomem? It can be. So this re-introduces the specialized memcpy_toio(), memcpy_fromio() and memset_io() functions. It doesn't particularly optimize them, but it tries to at least not be horrid, or do overlapping accesses. In fact, this uses the existing __inline_memcpy() function that we still had lying around that uses our very traditional "rep movsl" loop followed by movsw/movsb for the final bytes. Somebody may decide to try to improve on it, but if we've gone almost a decade with only one person really ever noticing and complaining, maybe it's not worth worrying about further, once it's not _completely_ broken?

2019-01-04Use __put_user_goto in __put_user_size() and unsafe_put_user()Linus Torvalds
This actually enables the __put_user_goto() functionality in unsafe_put_user(). For an example of the effect of this, this is the code generated for the unsafe_put_user(signo, &infop->si_signo, Efault); in the waitid() system call: movl %ecx,(%rbx) # signo, MEM[(struct __large_struct *)_2] It's just one single store instruction, along with generating an exception table entry pointing to the Efault label case in case that instruction faults. Before, we would generate this: xorl %edx, %edx movl %ecx,(%rbx) # signo, MEM[(struct __large_struct *)_3] testl %edx, %edx jne .L309 with the exception table generated for that 'mov' instruction causing us to jump to a stub that set %edx to -EFAULT and then jumped back to the 'testl' instruction. So not only do we now get rid of the extra code in the normal sequence, we also avoid unnecessarily keeping that extra error register live across it all.

2019-01-04x86 uaccess: Introduce __put_user_gotoLinus Torvalds
This is finally the actual reason for the odd error handling in the "unsafe_get/put_user()" functions, introduced over three years ago. Using a "jump to error label" interface is somewhat odd, but very convenient as a programming interface, and more importantly, it fits very well with simply making the target be the exception handler address directly from the inline asm. The reason it took over three years to actually do this? We need "asm goto" support for it, which only became the default on x86 last year. It's now been a year that we've forced asm goto support (see commit e501ce957a78 "x86: Force asm-goto"), and so let's just do it here too. [ Side note: this commit was originally done back in 2016. The above commentary about timing is obviously about it only now getting merged into my real upstream tree - Linus ] Sadly, gcc still only supports "asm goto" with asms that do not have any outputs, so we are limited to only the put_user case for this. Maybe in several more years we can do the get_user case too. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2019-01-05parisc: Remap hugepage-aligned pages in set_kernel_text_rw()Helge Deller
The alternative coding patch for parisc in kernel 4.20 broke booting machines with PA8500-PA8700 CPUs. The problem is, that for such machines the parisc kernel automatically utilizes huge pages to access kernel text code, but the set_kernel_text_rw() function, which is used shortly before applying any alternative patches, didn't used the correctly hugepage-aligned addresses to remap the kernel text read-writeable.

2019-01-04ixgbe: fix Kconfig when driver is not a moduleJeff Kirsher
The new ability added to the driver to use mii_bus to handle MII related ioctls is causing compile issues when the driver is compiled into the kernel (i.e. not a module). The problem was in selecting MDIO_DEVICE instead of the preferred PHYLIB Kconfig option. The reason being that MDIO_DEVICE had a dependency on PHYLIB and would be compiled as a module when PHYLIB was a module, no matter whether ixgbe was compiled into the kernel.

Commit ade446403bfb ("net: ipv4: do not handle duplicate fragments as overlapping") changed IPv4 defragmentation so that duplicate fragments, as well as _some_ fragments completely covered by previously delivered fragments, do not lead to the whole frag queue being discarded. This makes the existing ip_defrag selftest flaky. This patch * makes sure that negative IPv4 defrag tests generate truly overlapping fragments that trigger defrag queue drops; * tests that duplicate IPv4 fragments do not trigger defrag queue drops; * makes a couple of minor tweaks to the test aimed at increasing its code coverage and reduce flakiness.

swap_readpage() wants to do polling to bring in pages if asked to, but it doesn't mark the bio as being polled. Additionally, the looping around the blk_poll() check isn't correct - if we get a zero return, we should call io_schedule(), we can't just assume that the bio has completed. The regular bio->bi_private check should be used for that.

2019-01-04fs: don't open code lru_to_page()Nikolay Borisov
Multiple filesystems open code lru_to_page(). Rectify this by moving the macro from mm_inline (which is specific to lru stuff) to the more generic mm.h header and start using the macro where appropriate. No functional changes.
