Commit 26dda5769509 "tools/bootconfig: Cleanup bootconfig footer size calculations" replaced some expressions of type int with the BOOTCONFIG_FOOTER_SIZE macro, which expands to an expression of type size_t, which is unsigned. On 32-bit architectures with LFS enabled (i.e. off_t is 64-bit), the seek offset of -BOOTCONFIG_FOOTER_SIZE now turns into a positive value. Fix this by casting the size to off_t before negating it. Just in case someone changes BOOTCONFIG_MAGIC_LEN to have type size_t later, do the same thing to the seek offset of -BOOTCONFIG_MAGIC_LEN.

2025-08-20objtool/LoongArch: Get table size correctly if LTO is enabledTiezhu Yang1-0/+23
When compiling with LLVM and CONFIG_LTO_CLANG is set, there exist many objtool warnings "sibling call from callable instruction with modified stack frame". For this special case, the related object file shows that there is no generated relocation section '.rela.discard.tablejump_annotate' for the table jump instruction jirl, thus objtool can not know that what is the actual destination address. It needs to do something on the LLVM side to make sure that there is the relocation section '.rela.discard.tablejump_annotate' if LTO is enabled, but in order to maintain compatibility for the current LLVM compiler, this can be done in the kernel Makefile for now. Ensure it is aware of linker with LTO, '--loongarch-annotate-tablejump' needs to be passed via '-mllvm' to ld.lld. Before doing the above changes, it should handle the special case of the relocation section '.rela.discard.tablejump_annotate' to get the correct table size first, otherwise there are many objtool warnings and errors if LTO is enabled. There are many different rodata for each function if LTO is enabled, it is necessary to enhance get_rodata_table_size_by_table_annotate().

xfrm_policy.sh, nft_flowtable.sh, and vrf-xfrm-tests.sh use 'ip xfrm' with SHA-1, either 'auth sha1' or 'auth-trunc hmac(sha1)'. That requires CONFIG_CRYPTO_SHA1, which CONFIG_INET_ESP intentionally doesn't select (as per its help text). Previously, the config for these tests relied on CONFIG_CRYPTO_SHA1 being selected by the unrelated option CONFIG_IP_SCTP.

channels ncdevmem tests that the kernel correctly rejects attempts to deactivate queues with MPs bound. Make the configure_channels() test support combined channels. Currently it tries to set the queue counts to rx N tx N-1, which only makes sense for devices which have IRQs per ring type. Most modern devices used combined IRQs/channels with both Rx and Tx queues. Since the math is total Rx == combined+Rx setting Rx when combined is non-zero will be increasing the total queue count, not decreasing as the test intends. Note that the test would previously also try to set the Tx ring count to Rx - 1, for some reason. Which would be 0 if the device has only 2 queues configured.

2025-08-19selftests/mm: add test for invalid multi VMA operationsLorenzo Stoakes1-3/+261
We can use UFFD to easily assert invalid multi VMA moves, so do so, asserting expected behaviour when VMAs invalid for a multi VMA operation are encountered. We assert both that such operations are not permitted, and that we do not even attempt to move the first VMA under these circumstances. We also assert that we can still move a single VMA regardless. We then assert that a partial failure can occur if the invalid VMA appears later in the range of multiple VMAs, both at the very next VMA, and also at the end of the range. As part of this change, we are using the is_range_valid() helper more aggressively. Therefore, fix a bug where stale buffered data would hang around on success, causing subsequent calls to is_range_valid() to potentially give invalid results. We simply have to fflush() the stream on success to resolve this issue.

Check that the return value of KVM_GET_VCPU_MMAP_SIZE is non-negative before comparing with sizeof(kvm_run). If KVM_GET_VCPU_MMAP_SIZE fails, it will return -1, and `-1 > sizeof(kvm_run)` is true, so the ASSERT passes. There are no other locations in tools/testing/selftests/kvm that make the same mistake.

2025-08-19bpftool: Add kernel.kptr_restrict hint for no instructionsVincent Li1-1/+1
From bpftool's github repository issue [0]: When a Linux distribution has the kernel.kptr_restrict set to 2, bpftool prog dump jited returns "no instructions returned". This message can be puzzling to bpftool users who are not familiar with kernel BPF internals, so add a small hint for bpftool users to check the kernel.kptr_restrict setting similar to the DUMP_XLATED case. Outside of kernel.kptr_restrict, no instructions could also be returned in case the JIT was disabled.

This modification is linked to the parent commit where the received ADD_ADDR limit was accidentally reset when the endpoints were flushed. To validate that, the test is now flushing endpoints after having set new limits, and before checking them. The 'Fixes' tag here below is the same as the one from the previous commit: this patch here is not fixing anything wrong in the selftests, but it validates the previous fix for an issue introduced by this commit ID.
