2024-02-29linux-user: Remove qemu_host_page_size from create_elf_tablesRichard Henderson
AT_PAGESZ is supposed to advertise the guest page size. The random adjustment made here using qemu_host_page_size does not match anything else within linux-user. The idea here is good, but should be done more systemically via adjustment to TARGET_PAGE_SIZE.

2024-02-29linux-user: Remove qemu_host_page_{size, mask} in probe_guest_baseRichard Henderson
The host SHMLBA is by definition a multiple of the host page size. Thus the remaining component of qemu_host_page_size is the target page size.

2024-02-29linux-user/elfload: Unprotect regions before core dumpRichard Henderson
By unprotecting regions, we re-instate writability and unify regions that have been split, which may reduce the total number of regions. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-29linux-user/elfload: Rely on walk_memory_regions for vmasRichard Henderson
Rather than creating new data structures for vma, rely on the IntervalTree used by walk_memory_regions. Use PAGE_* constants, per the page table api, rather than PROT_* constants, per the mmap api. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-29linux-user/elfload: Simplify vma_dump_sizeRichard Henderson
Use the flags that we've already saved in order to test accessibility. Use g2h_untagged and compare guest memory directly instead of copy_from_user. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-29linux-user/elfload: Write process memory to core file in larger chunksRichard Henderson
We do not need to copy pages from guest memory before writing them out. Because vmas are contiguous in host memory, we can write them in one go. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-29linux-user/elfload: Write corefile elf header in one blockRichard Henderson
Fixes a bug in which write_note() wrote namesz_rounded and datasz_rounded bytes, even though name and data pointers contain only the unrounded number of bytes. Instead of many small writes, allocate a block to contain all of the elf headers and all of the notes. Copy the data into the block piecemeal and the write it to the file as a chunk. This also avoids the need to lseek forward for alignment. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-29linux-user/elfload: Size corefile before openingRichard Henderson
Verify the size of the corefile vs the rlimit before opening and creating the core file at all. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

Do not allow changes to the set of cpus and memory regions while we are dumping core. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-29linux-user/elfload: Truncate core file on openRichard Henderson
While we usually create a new corefile, truncate otherwise. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-29linux-user/elfload: Open core file after vma_initRichard Henderson
Swap the ordering of vma_init and open. This will be necessary for further changes, and adjusts the error cleanup path. Narrow the scope of corefile, as the variable can be freed immediately after use in open(). Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-29linux-user/elfload: Latch errno before cleanup in elf_core_dumpRichard Henderson
On the off-chance that one of the cleanup functions changes errno, latch the errno that we want to return beforehand. Flush errno to 0 upon success, rather than at the beginning. No need to avoid negation of 0. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-29linux-user/elfload: Stack allocate struct mm_structRichard Henderson
Ignoring the fact that g_malloc cannot fail, the structure is quite small and might as well be allocated locally. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-29linux-user/elfload: Tidy fill_note_info and struct elf_note_infoRichard Henderson
In fill_note_info, there were unnecessary checks for success of g_new/g_malloc. But these structures do not need to be dyamically allocated at all, and can in fact be statically allocated within the parent structure. This removes all error paths from fill_note_info, so change the return type to void. Change type of signr to match both caller (elf_core_dump) and callee (fill_prstatus), which both use int for signr. Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2024-02-29linux-user/elfload: Disable core dump if getrlimit failsRichard Henderson
Do not dump core at all if getrlimit fails; this ensures that dumpsize is valid throughout the function, not just for the initial test vs rlim_cur. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
2024-02-28linux-user: ensure nios2 processes queued workAlex Bennée
While async processes are rare for linux-user we do use them from time to time. The most obvious one is tb_flush when we run out of translation space. We will also need this when we move plugin vcpu_init to an async task. Fix nios2 to follow its older, wiser and more stable siblings.

A process can opt-out of coredump creation by calling prctl(PR_SET_DUMPABLE, 0). linux-user passes this call from the guest through to the operating system.

The result is that all linux-users invocations that doesn't specify a different CPU started to show a deprecation warning: $ ./build/qemu-riscv64 ./foo-novect.out qemu-riscv64: warning: The 'any' CPU is deprecated and will be removed in the future. Change the default CPU for RISC-V linux-user from 'any' to 'max'.

2023-11-05target/sparc: Split psr and xcc into componentsRichard Henderson
Step in removing CC_OP: change the representation of CC_OP_FLAGS. The 8 bits are distributed between 6 variables, which should make it easy to keep up to date. The code within cc_helper.c is quite ugly but is only temporary.
