samples/bpf: Fix a resource leak

kfifo: don't include dma-mapping.h in kfifo.h

2024-12-05T13:03:03Z

[ Upstream commit 44059790a5cb9258ae6137387e4c39b717fd2ced ] Nothing in kfifo.h directly needs dma-mapping.h, only two macros use DMA_MAPPING_ERROR when actually instantiated. Drop the dma-mapping.h include to reduce include bloat. Add an explicity include to drivers/mailbox/omap-mailbox.c as that file uses __raw_readl and __raw_writel through a complicated include chain involving Fixes: d52b761e4b1a ("kfifo: add kfifo_dma_out_prepare_mapped()") Signed-off-by: Christoph Hellwig Link: https://lore.kernel.org/r/20241023055317.313234-1-hch@lst.de Signed-off-by: Greg Kroah-Hartman Signed-off-by: Sasha Levin

bpf: Fix the xdp_adjust_tail sample prog issue

2024-12-05T13:01:42Z

[ Upstream commit 4236f114a3ffbbfd217436c08852e94cae372f57 ] During the xdp_adjust_tail test, probabilistic failure occurs and SKB package is discarded by the kernel. After checking the issues by tracking SKB package, it is identified that they were caused by checksum errors. Refer to checksum of the arch/arm64/include/asm/checksum.h for fixing. v2: Based on Alexei Starovoitov's suggestions, it is necessary to keep the code implementation consistent.

samples: pktgen: correct dev to DEV

2024-11-14T02:54:33Z

In the pktgen_sample01_simple.sh script, the device variable is uppercase 'DEV' instead of lowercase 'dev'. Because of this typo, the script cannot enable UDP tx checksum.

samples/landlock: Clarify option parsing behaviour

2024-10-22T18:43:43Z

Clarify the distinction between filesystem variables (mandatory) and all others (optional). For optional variables, explain the difference between unset variables (no access check performed) and empty variables (nothing allowed for lists of allowed paths/ports, or no effect for lists of scopes). List the known LL_SCOPED values and their effect.

samples/landlock: Refactor help message

2024-10-22T18:43:43Z

Help message is getting larger with each new supported feature (scopes, and soon UDP). Also the large number of calls to fprintf with environment variables make it hard to read. Refactor it away into a single simpler constant format string.

samples/landlock: Fix port parsing in sandboxer

2024-10-22T18:43:41Z

If you want to specify that no port can be bind()ed, you would think (looking quickly at both help message and code) that setting LL_TCP_BIND="" would do it. However the code splits on ":" then applies atoi(), which does not allow checking for errors. Passing an empty string returns 0, which is interpreted as "allow bind(0)", which means bind to any ephemeral port. This bug occurs whenever passing an empty string or when leaving a trailing/leading colon, making it impossible to completely deny bind(). To reproduce: export LL_FS_RO="/" LL_FS_RW="" LL_TCP_BIND="" ./sandboxer strace -e bind nc -n -vvv -l -p 0 Executing the sandboxed command... bind(3, {sa_family=AF_INET, sin_port=htons(0), sin_addr=inet_addr("0.0.0.0")}, 16) = 0 Listening on 0.0.0.0 37629 Use strtoull(3) instead, which allows error checking. Check that the entire string has been parsed correctly without overflows/underflows, but not that the __u64 (the type of struct landlock_net_port_attr.port) is a valid __u16 port: that is already done by the kernel.

[tree-wide] finally take no_llseek out

2024-09-27T15:18:43Z

no_llseek had been defined to NULL two years ago, in commit 868941b14441 ("fs: remove no_llseek") To quote that commit, At -rc1 we'll need do a mechanical removal of no_llseek - git grep -l -w no_llseek | grep -v porting.rst | while read i; do sed -i '/\/d' $i done would do it. Unfortunately, that hadn't been done. Linus, could you do that now, so that we could finally put that thing to rest? All instances are of the form .llseek = no_llseek, so it's obviously safe.

Pull landlock updates from Mickaël Salaün: "We can now scope a Landlock domain thanks to a new "scoped" field that can deny interactions with resources outside of this domain. The LANDLOCK_SCOPE_ABSTRACT_UNIX_SOCKET flag denies connections to an abstract UNIX socket created outside of the current scoped domain, and the LANDLOCK_SCOPE_SIGNAL flag denies sending a signal to processes outside of the current scoped domain. These restrictions also apply to nested domains according to their scope.
