2022-07-02net: pcs: rzn1-miic: update speed only if interface is changedClément Léger1-5/+16
As stated by Russel King, miic_config() can be called as a result of ethtool setting the configuration while the link is already up. Since the speed is also set in this function, it could potentially modify the current speed that is set. This will only happen if there is no PHY present and we aren't using fixed-link mode. Handle that by storing the current interface mode in the miic_port structure and update the speed only if the interface mode is going to be changed.

Issue reported on Juno with HDLCD clock which turned out to be yet another firmware issue. The firmware is not conformant to the spec and we now have to workaround as this may be copied to other platforms as well. The spec expects to return size of 3 for a range clock rate description while the firmware returns 1. We have other ways to validate all the 3 entries the driver reads are polpulated and we use the same to workaround this firmware bug. 2. Optee transport not setting the correct reponse length which is similar to the one reported earlier on Rockchip platform. 3.

2022-07-01bpf: Fix insufficient bounds propagation from adjust_scalar_min_max_valsDaniel Borkmann1-49/+23
Kuee reported a corner case where the tnum becomes constant after the call to __reg_bound_offset(), but the register's bounds are not, that is, its min bounds are still not equal to the register's max bounds. This in turn allows to leak pointers through turning a pointer register as is into an unknown scalar via adjust_ptr_min_max_vals().

Intersecting with var_off has not been done at that point via __update_reg_bounds(), which would have improved the umax to be equal to umin. Refactor the tnum <> min/max bounds information flow into a reg_bounds_sync() helper and use it consistently everywhere. After the fix, bounds have been corrected to R3_w=scalar(imm=0,umax=0,var_off=(0x0; 0x0)) and thus the register is regarded as a 'proper' constant scalar of 0.

2022-07-01bpf: Fix incorrect verifier simulation around jmp32's jeq/jneDaniel Borkmann1-17/+24
Kuee reported a quirk in the jmp32's jeq/jne simulation, namely that the register value does not match expectations for the fall-through path. For example: Before fix: 0: R1=ctx(off=0,imm=0) R10=fp0 0: (b7) r2 = 0 ; R2_w=P0 1: (b7) r6 = 563 ; R6_w=P563 2: (87) r2 = -r2 ; R2_w=Pscalar() 3: (87) r2 = -r2 ; R2_w=Pscalar() 4: (4c) w2 |= w6 ; R2_w=Pscalar(umin=563,umax=4294967295,var_off=(0x233; 0xfffffdcc),s32_min=-2147483085) R6_w=P563 5: (56) if w2 != 0x8 goto pc+1 ; R2_w=P571 <--- [*] 6: (95) exit R0 !read_ok After fix: 0: R1=ctx(off=0,imm=0) R10=fp0 0: (b7) r2 = 0 ; R2_w=P0 1: (b7) r6 = 563 ; R6_w=P563 2: (87) r2 = -r2 ; R2_w=Pscalar() 3: (87) r2 = -r2 ; R2_w=Pscalar() 4: (4c) w2 |= w6 ; R2_w=Pscalar(umin=563,umax=4294967295,var_off=(0x233; 0xfffffdcc),s32_min=-2147483085) R6_w=P563 5: (56) if w2 != 0x8 goto pc+1 ; R2_w=P8 <--- [*] 6: (95) exit R0 !read_ok As can be seen on line 5 for the branch fall-through path in R2 [*] is that given condition w2 != 0x8 is false, verifier should conclude that r2 = 8 as upper 32 bit are known to be zero. However, verifier incorrectly concludes that r2 = 571 which is far off. The problem is it only marks false{true}_reg as known in the switch for JE/NE case, but at the end of the function, it uses {false,true}_{64,32}off to update {false,true}_reg->var_off and they still hold the prior value of {false,true}_reg->var_off before it got marked as known. The subsequent __reg_combine_32_into_64() then propagates this old var_off and derives new bounds. The information between min/max bounds on {false,true}_reg from setting the register to known const combined with the {false,true}_reg->var_off based on the old information then derives wrong register data. Fix it by detangling the BPF_JEQ/BPF_JNE cases and updating relevant {false,true}_{64,32}off tnums along with the register marking to known constant.

2022-07-01arm64: hugetlb: Restore TLB invalidation for BBM on contiguous ptesWill Deacon1-9/+21
Commit fb396bb459c1 ("arm64/hugetlb: Drop TLB flush from get_clear_flush()") removed TLB invalidation from get_clear_flush() [now get_clear_contig()] on the basis that the core TLB invalidation code is aware of hugetlb mappings backed by contiguous page-table entries and will cover the correct virtual address range. However, this change also resulted in the TLB invalidation being removed from the "break" step in the break-before-make (BBM) sequence used internally by huge_ptep_set_{access_flags,wrprotect}(), therefore making the BBM sequence unsafe irrespective of later invalidation. Although the architecture is desperately unclear about how exactly contiguous ptes should be updated in a live page-table, restore TLB invalidation to our BBM sequence under the assumption that BBM is the right thing to be doing in the first place.

When generic/475 runs, it starts fsstress in the background, waits a few seconds, and substitutes a dm-error device to simulate a disk falling out of a machine. If the fsstress encounters EIO on a pure data write, it will exit but the filesystem will still be online. The next thing the test does is unmount the filesystem, which tries to clean the log, free the CIL, and wait for iclog IO completion. If an iclog was being written when the dm-error switch occurred, it can race with log unmounting as follows: Thread 1 Thread 2 xfs_log_unmount xfs_log_clean xfs_log_quiesce xlog_ioend_work <observe error> xlog_force_shutdown test_and_set_bit(XLOG_IOERROR) xfs_log_force <log is shut down, nop> xfs_log_umount_write <log is shut down, nop> xlog_dealloc_log xlog_cil_destroy <wait for iclogs> spin_lock(&log->l_cilp->xc_push_lock) <KABOOM> Therefore, free the CIL after waiting for the iclogs to complete. I /think/ this race has existed for quite a few years now, though I don't remember the ~2014 era logging code well enough to know if it was a real threat then or if the actual race was exposed only more recently.
