2024-05-07gpiolib: Discourage to use formatting strings in line namesAndy Shevchenko
Currently the documentation for line names allows to use %u inside the alternative name. This is broken in character device approach from day 1 and being in use solely in sysfs. Character device interface has a line number as a part of its address, so the users better rely on it. Hence remove the misleading documentation. On top of that, there are no in-kernel users (out of 6, if I'm correct) for such names and moreover if one exists it won't help in distinguishing lines with the same naming as '%u' will also be in them and we will get a warning in gpiochip_set_desc_names() for such cases.

2024-05-06octeontx2-pf: Treat truncation of IRQ name as an errorSimon Horman
According to GCC, the constriction of irq_name in otx2_open() may, theoretically, be truncated.

Peter Griffin <peter.griffin@linaro.org> says: Hi Martin, James & Alim, This series adds support to the ufs-exynos driver for Tensor gs101 found in Pixel 6. It was send previously in [1] and [2] but included the other clock, phy and DTS parts. This series has been split into just the ufs-exynos part to hopefully make things easier. With this series, plus the phy, clock and dts changes UFS is functional upstream for Pixel 6. The SKhynix HN8T05BZGKX015 can be enumerated, partitions mounted etc. The series is split into some prepatory patches for ufs-exynos and a final patch that adds the gs101 support. Note the sysreg clock has been moved to ufs node as fine grained clock control around the syscon sysreg register accesses doesn't result in functional UFS. regards, Peter Link: https://lore.kernel.org/r/20240426122004.2249178-1-peter.griffin@linaro.org Signed-off-by: Martin K.

On x86_64 and allmodconfig, this shrinks the size of 'struct regmap_config' from 328 to 312 bytes. This is usually a win, because this structure is used as a static global variable. When moving the kerneldoc fields, I've tried to keep the layout as consistent as possible, which is not really easy! Before: /* size: 328, cachelines: 6, members: 55 */ /* sum members: 296, holes: 6, sum holes: 25 */ /* padding: 7 */ /* last cacheline: 8 bytes */ After: /* size: 312, cachelines: 5, members: 55 */ /* sum members: 296, holes: 5, sum holes: 16 */ /* last cacheline: 56 bytes */ For the records, this is also widely used: $git grep static.*regmap_config | wc -l 1327 Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/5e039cd8fe415dd7ab3169948c08a5311db9fb9a.1715024007.git.christophe.jaillet@wanadoo.fr Signed-off-by: Mark Brown <broonie@kernel.org>

Currently, we allocate a count-sized kernel buffer and copy count from userspace to that buffer. Later, we use kstrtouint on this buffer but we don't ensure that the string is terminated inside the buffer, this can lead to OOB read when using kstrtouint.

Cupertino Miranda says: ==================== bpf/verifier: range computation improvements Hi everyone, This is what I hope to be the last version. :) Regards, Cupertino Changes from v1: - Reordered patches in the series. - Fix refactor to be acurate with original code. - Fixed other mentioned small problems. Changes from v2: - Added a patch to replace mark_reg_unknowon for __mark_reg_unknown in the context of range computation. - Reverted implementation of refactor to v1 which used a simpler boolean return value in check function. - Further relaxed MUL to allow it to still compute a range when neither of its registers is a known value. - Simplified tests based on Eduards example. - Added messages in selftest commits. Changes from v3: - Improved commit message of patch nr 1. - Coding style fixes. - Improve XOR and OR tests. - Made function calls to pass struct bpf_reg_state pointer instead. - Improved final code as a last patch. Changes from v4: - Merged patch nr 7 in 2. ==================== Link: https://lore.kernel.org/r/20240506141849.185293-1-cupertino.miranda@oracle.com Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2024-05-06bpf/verifier: relax MUL range computation checkCupertino Miranda
MUL instruction required that src_reg would be a known value (i.e. src_reg would be a const value). The condition in this case can be relaxed, since the range computation algorithm used in current code already supports a proper range computation for any valid range value on its operands.

2024-05-06bpf/verifier: replace calls to mark_reg_unknown.Cupertino Miranda
In order to further simplify the code in adjust_scalar_min_max_vals all the calls to mark_reg_unknown are replaced by __mark_reg_unknown. static void mark_reg_unknown(struct bpf_verifier_env *env, struct bpf_reg_state *regs, u32 regno) { if (WARN_ON(regno >= MAX_BPF_REG)) { ... mark all regs not init ... return; } __mark_reg_unknown(env, regs + regno); } The 'regno >= MAX_BPF_REG' does not apply to adjust_scalar_min_max_vals(), because it is only called from the following stack: - check_alu_op - adjust_reg_min_max_vals - adjust_scalar_min_max_vals The check_alu_op() does check_reg_arg() which verifies that both src and dst register numbers are within bounds.
