[PATCH] MIPS: Expand MIPS32 ASIDs to 64 bits

by Paul Burton

ASIDs have always been stored as unsigned longs, ie. 32 bits on MIPS32 kernels. This is problematic because it is feasible for the ASID version to overflow & wrap around to zero. We currently attempt to handle this overflow by simply setting the ASID version to 1, using asid_first_version(), but we make no attempt to account for the fact that there may be mm_structs with stale ASIDs that have versions which we now reuse due to the overflow & wrap around. Encountering this requires that: 1) A struct mm_struct X is active on CPU A using ASID (V,n). 2) That mm is not used on CPU A for the length of time that it takes for CPU A's asid_cache to overflow & wrap around to the same version V that the mm had in step 1. During this time tasks using the mm could either be sleeping or only scheduled on other CPUs. 3) Some other mm Y becomes active on CPU A and is allocated the same ASID (V,n). 4) mm X now becomes active on CPU A again, and now incorrectly has the same ASID as mm Y. Where struct mm_struct ASIDs are represented above in the format (version, EntryHi.ASID), and on a typical MIPS32 system version will be 24 bits wide & EntryHi.ASID will be 8 bits wide. The length of time required in step 2 is highly dependent upon the CPU & workload, but for a hypothetical 2GHz CPU running a workload which generates a new ASID every 10000 cycles this period is around 248 days. Due to this long period of time & the fact that tasks need to be scheduled in just the right (or wrong, depending upon your inclination) way, this is obviously a difficult bug to encounter but it's entirely possible as evidenced by reports. In order to fix this, simply extend ASIDs to 64 bits even on MIPS32 builds. This will extend the period of time required for the hypothetical system above to encounter the problem from 28 days to around 3 trillion years, which feels safely outside of the realms of possibility. The cost of this is slightly more generated code in some commonly executed paths, but this is pretty minimal: | Code Size Gain | Percentage -----------------------|----------------|------------- decstation_defconfig | +270 | +0.00% 32r2el_defconfig | +652 | +0.01% 32r6el_defconfig | +1000 | +0.01% I have been unable to measure any change in performance of the LMbench lat_ctx or lat_proc tests resulting from the 64b ASIDs on either 32r2el_defconfig+interAptiv or 32r6el_defconfig+I6500 systems.

by akpm＠linux-foundation.org

The patch titled Subject: proc/sysctl: don't return ENOMEM on lookup when a table is unregistering has been added to the -mm tree. Its filename is proc-sysctl-dont-return-enomem-on-lookup-when-a-table-is-unregistering.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/proc-sysctl-dont-return-enomem-on-… and later at http://ozlabs.org/~akpm/mmotm/broken-out/proc-sysctl-dont-return-enomem-on-… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Ivan Delalande <colona(a)arista.com> Subject: proc/sysctl: don't return ENOMEM on lookup when a table is unregistering proc_sys_lookup can fail with ENOMEM instead of ENOENT when the corresponding sysctl table is being unregistered. In our case we see this upon opening /proc/sys/net/*/conf files while network interfaces are being deleted, which confuses our configuration daemon. The problem was successfully reproduced and this fix tested on v4.9.122 and v4.20-rc6.
