Subject: [PATCH v4 0/3] linux-user: Allow gdbstub to ignore page protection
Date: Mon, 29 Jan 2024 10:32:13 +0100 [thread overview]
Message-ID: <20240129093410.3151-1-iii@linux.ibm.com> (raw)
v3: https://lists.gnu.org/archive/html/qemu-devel/2024-01/msg02907.html
v3 -> v4: Hide InteractiveConsole behind QEMU_TEST_INTERACTIVE (Alex).
Probe /proc/self/mem in the PROT_NONE test.
v2: https://lists.gnu.org/archive/html/qemu-devel/2024-01/msg01592.html
v2 -> v3: Add Richard's R-b on [1/3].
Fix printing the architecture name and the number of failures
in test_gdbstub.py.
Patches that need review: [2/3] and [3/3].
v1: https://lists.gnu.org/archive/html/qemu-devel/2024-01/msg01314.html
v1 -> v2: Use /proc/self/mem as a fallback. Handle TB invalidation
(Richard).
Test cross-page accesses.
RFC: https://lists.gnu.org/archive/html/qemu-devel/2023-12/msg02044.html
RFC -> v1: Use /proc/self/mem and accept that this will not work
without /proc.
Factor out a couple functions for gdbstub testing.
Add a test.
Hi,
I've noticed that gdbstub behaves differently from gdbserver in that it
doesn't allow reading non-readable pages. This series improves the
situation by using the same mechanism as gdbserver: /proc/self/mem.
Best regards,
Ilya
