2019-10-23RDMA/core: Check that process is still alive before sending it to the usersLeon Romanovsky2-9/+33
The PID information can disappear asynchronously because the task can be killed and moved to zombie state. In this case, PID will be zero in similar way to the kernel tasks. Recognize such situation where we are asking to return orphaned object and simply skip filling PID attribute. As part of this change, document the same scenario in counter.c code.

2019-10-23RDMA/restrack: Remove PID namespace supportLeon Romanovsky4-46/+2
IB resources are bounded to IB device and file descriptors, both entities are unaware to PID namespaces and to task lifetime. The difference in model caused to unpredictable behavior for the following scenario: 1. Create FD and context 2. Share it with ephemeral child 3. Create any object and exit that child The end result of this flow, that those newly created objects will be tracked by restrack, but won't be visible for users because task_struct associated with them already exited. The right thing is to rely on net namespace only for any filtering purposes and drop PID namespace.

2019-10-22RDMA/mlx5: Add capability for max sge to get optimized performanceYamin Friedman1-0/+2
Allows the IB device to provide a value of maximum scatter gather entries per RDMA READ. In certain cases it may be preferable for a device to perform UMR memory registration rather than have many scatter entries in a single RDMA READ. This provides a significant performance increase in devices capable of using different memory registration schemes based on the number of scatter gather entries. This general capability allows each device vendor to fine tune when it is better to use memory registration.

The default maximum immediate size is too big for old srp clients, which do not support immediate data. According to the SRP and SRP-2 specifications, the IOControllerProfile attributes for SRP target ports contains the maximum initiator to target iu length. The maximum initiator to target iu length can be obtained by sending MAD packets to query subnet manager port and SRP target ports. We should calculate the max_it_iu_size instead of the default value, when remote maximum initiator to target iu length available.

2019-10-08RDMA/srp: Add parse function for maximum initiator to target IU sizeHonggang Li3-0/+13
According to SRP specifications 'srp-r16a' and 'srp2r06', IOControllerProfile attributes for SRP target port include the maximum initiator to target IU size. SRP connection daemons, such as srp_daemon, can get the value from the subnet manager. The SRP connection daemon can pass this value to kernel. This patch adds a parse function for it. Upstream commit [1] enables the kernel parameter, 'use_imm_data', by default. [1] also use (8 * 1024) as the default value for kernel parameter 'max_imm_data'. With those default values, the maximum initiator to target IU size will be 8260. In case the SRPT modules, which include the in-tree 'ib_srpt.ko' module, do not support SRP-2 'immediate data' feature, the default maximum initiator to target IU size is significantly smaller than 8260. For 'ib_srpt.ko' module, which built from source before [2], the default maximum initiator to target IU is 2116. [1] introduces a regression issue for old srp targets with default kernel parameters, as the connection will be rejected because of a too large maximum initiator to target IU size.

2019-10-06elf: don't use MAP_FIXED_NOREPLACE for elf executable mappingsLinus Torvalds1-10/+3
In commit 4ed28639519c ("fs, elf: drop MAP_FIXED usage from elf_map") we changed elf to use MAP_FIXED_NOREPLACE instead of MAP_FIXED for the executable mappings. Then, people reported that it broke some binaries that had overlapping segments from the same file, and commit ad55eac74f20 ("elf: enforce MAP_FIXED on overlaying elf segments") re-instated MAP_FIXED for some overlaying elf segment cases. But only some - despite the summary line of that commit, it only did it when it also does a temporary brk vma for one obvious overlapping case. Now Russell King reports another overlapping case with old 32-bit x86 binaries, which doesn't trigger that limited case. End result: we had better just drop MAP_FIXED_NOREPLACE entirely, and go back to MAP_FIXED. Yes, it's a sign of old binaries generated with old tool-chains, but we do pride ourselves on not breaking existing setups. This still leaves MAP_FIXED_NOREPLACE in place for the load_elf_interp() and the old load_elf_library() use-cases, because nobody has reported breakage for those. Yet. Note that in all the cases seen so far, the overlapping elf sections seem to be just re-mapping of the same executable with different section attributes. We could possibly introduce a new MAP_FIXED_NOFILECHANGE flag or similar, which acts like NOREPLACE, but allows just remapping the same executable file using different protection flags. It's not clear that would make a huge difference to anything, but if people really hate that "elf remaps over previous maps" behavior, maybe at least a more limited form of remapping would alleviate some concerns. Alternatively, we should take a look at our elf_map() logic to see if we end up not mapping things properly the first time. In the meantime, this is the minimal "don't do that then" patch while people hopefully think about it more.

2019-10-05Make filldir[64]() verify the directory entry filename is validLinus Torvalds1-0/+40
This has been discussed several times, and now filesystem people are talking about doing it individually at the filesystem layer, so head that off at the pass and just do it in getdents{64}(). This is partially based on a patch by Jann Horn, but checks for NUL bytes as well, and somewhat simplified. There's also commentary about how it might be better if invalid names due to filesystem corruption don't cause an immediate failure, but only an error at the end of the readdir(), so that people can still see the filenames that are ok. There's also been discussion about just how much POSIX strictly speaking requires this since it's about filesystem corruption. It's really more "protect user space from bad behavior" as pointed out by Jann. But since Eric Biederman looked up the POSIX wording, here it is for context: "From readdir: The readdir() function shall return a pointer to a structure representing the directory entry at the current position in the directory stream specified by the argument dirp, and position the directory stream at the next entry. It shall return a null pointer upon reaching the end of the directory stream. The structure dirent defined in the <dirent.h> header describes a directory entry. From definitions: 3.129 Directory Entry (or Link) An object that associates a filename with a file. Several directory entries can associate names with the same file. ... 3.169 Filename A name consisting of 1 to {NAME_MAX} bytes used to name a file. The characters composing the name may be selected from the set of all character values excluding the slash character and the null byte. The filenames dot and dot-dot have special meaning. A filename is sometimes referred to as a 'pathname component'." Note that I didn't bother adding the checks to any legacy interfaces that nobody uses. Also note that if this ends up being noticeable as a performance regression, we can fix that to do a much more optimized model that checks for both NUL and '/' at the same time one word at a time. We haven't really tended to optimize 'memchr()', and it only checks for one pattern at a time anyway, and we really _should_ check for NUL too (but see the comment about "soft errors" in the code about why it currently only checks for '/') See the CONFIG_DCACHE_WORD_ACCESS case of hash_name() for how the name lookup code looks for pathname terminating characters in parallel.

2019-10-05Convert filldir[64]() from __put_user() to unsafe_put_user()Linus Torvalds1-35/+93
We really should avoid the "__{get,put}_user()" functions entirely, because they can easily be mis-used and the original intent of being used for simple direct user accesses no longer holds in a post-SMAP/PAN world. Manually optimizing away the user access range check makes no sense any more, when the range check is generally much cheaper than the "enable user accesses" code that the __{get,put}_user() functions still need. So instead of __put_user(), use the unsafe_put_user() interface with user_access_{begin,end}() that really does generate better code these days, and which is generally a nicer interface. Under some loads, the multiple user writes that filldir() does are actually quite noticeable. This also makes the dirent name copy use unsafe_put_user() with a couple of macros. We do not want to make function calls with SMAP/PAN disabled, and the code this generates is quite good when the architecture uses "asm goto" for unsafe_put_user() like x86 does. Note that this doesn't bother with the legacy cases. Nobody should use them anyway, so performance doesn't really matter there. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2019-10-05kheaders: make headers archive reproducibleDmitry Goldin2-5/+13
In commit 43d8ce9d65a5 ("Provide in-kernel headers to make extending kernel easier") a new mechanism was introduced, for kernels >=5.2, which embeds the kernel headers in the kernel image or a module and exposes them in procfs for use by userland tools. The archive containing the header files has nondeterminism caused by header files metadata. This patch normalizes the metadata and utilizes KBUILD_BUILD_TIMESTAMP if provided and otherwise falls back to the default behaviour. In commit f7b101d33046 ("kheaders: Move from proc to sysfs") it was modified to use sysfs and the script for generation of the archive was renamed to what is being patched.
