  "message": "lakitu_defconfig: make /proc/self/mem read-write\n\nThe behavior was inherited from ChromeOS change (see [1], [2]). The\nChromeOS deicion to make the file read-only was based on the following\nassumptions:\n - There is no valid use case for the process to write to the /dev/self/mem\n - The ptrace API that can be used to circumvent the limitation\n   also could be disabled system-wide because there was\n\nThese assumptions are not true for COS, since debugging is a valid use\ncase and therefor ptrace can\u0027t be disabled. Which removes a large share\nof the value of having /dev/self/mem read-only.\n\nIn addition to this recent versions of gdb stopped working on COS\nbecause gdb switched from using ptrace to directly modifying process\nmemory through the mem file. This is a significant user experience\nregression.\n\nSince there are more cons than pros to keeping the ChromeOS behavior\nenabled, this commit reverts the access mode to default (r/w).\n\n[1] https://bugs.chromium.org/p/chromium/issues/detail?id\u003d781376\n[2] https://chromium-review.googlesource.com/c/chromiumos/third_party/kernel/+/753406\n\nBUG\u003db/285213716\nTEST\u003dpresubmit\nRELEASE_NOTE\u003dnone\n\nChange-Id: I8ddc7ed04ee5b26e0b6d43a3f790854d226f23d5\nReviewed-on: https://cos-review.googlesource.com/c/third_party/kernel/+/52034\nReviewed-by: Robert Kolchmeyer \u003crkolchmeyer@google.com\u003e\nTested-by: Oleksandr Tymoshenko \u003covt@google.com\u003e\nReviewed-by: Vaibhav Rustagi \u003cvaibhavrustagi@google.com\u003e\n",
