* cmd: correct long text loadb, loadx, loadyHeinrich Schuchardt2021-01-251-6/+6

* cmd: change suppress newline in echo commandHeinrich Schuchardt2021-01-251-31/+18
| | | | | | | | | | | | | | | | | | | | | | By default the echo command emits its arguments followed by a line feed. If any of the arguments contains the sub-string "\c", the line feed is suppressed. This does not match shells used in Linux and BSD where the first argument has to be -n to suppress the line feed. The hush shell interferes with the parsing of backslashes. E.g. in the following command line quadruple backslashes are required for suppressing the line feed: for i in 1 2 3; do for j in 4 5; do echo \\\\c ${i}${j}; done; echo; done; To avoid unexpected behavior the patch changes echo to use -n as first argument to suppress the line feed.

* cmd: efidebug: always check return code from get_variable()AKASHI Takahiro2021-01-231-5/+7
| | | | | | | | | | | | | | | | | | | | | CID 316364 says: > Null pointer dereferences (FORWARD_NULL) > printf("Result total size: 0x%x\n", result->variable_total_size); at do_efi_capsule_res(). The code is basically safe because a buffer for "result" is allocated by malloc() and filled up by the second get_variable(), which fails any way if the allocation has failed. But the first (and second) get_variable() possibly returns an error other than EFI_SUCCESS. We always need to check the return code from get_variable() before accessing the data in "result". While this change won't suppress CID 316364, the resulting code is much safer. Signed-off-by: AKASHI Takahiro <takahiro.akashi@linaro.org> Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

* cmd: Add MBR partition layout control utilityMarek Szyprowski2021-01-153-0/+323
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a 'mbr' command to let users create or verify MBR partition layout based on the provided text description. The partition layout is alternatively read from the 'mbr_parts' environment variable. This can be used in scripts to help system image flashing tools to ensure proper partition layout. The syntax of the text description of the partition list is similar to the one used by the 'gpt' command. Supported parameters are: name (currently ignored), start (partition start offset in bytes), size (in bytes or '-' to expand it to the whole free area), bootable (boolean flag) and id (MBR partition type). If one wants to create more than 4 partitions, an 'Extended' primary partition (with 0x05 ID) has to be explicitely provided as a one of the first 4 entries. Here is an example how to create a 6 partitions (3 on the 'extended volume'), some of the predefined sizes: > setenv mbr_parts 'name=boot,start=4M,size=128M,bootable,id=0x0e; name=rootfs,size=3072M,id=0x83; name=system-data,size=512M,id=0x83; name=[ext],size=-,id=0x05; name=user,size=-,id=0x83; name=modules,size=100M,id=0x83; name=ramdisk,size=8M,id=0x83' > mbr write mmc 0 Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com>

But in the latter case it provides no indication of what went wrong. If an attempt is made to delete a non-existent variable, the caller may want to ignore this error.

Make sure that env_set() does not return an error if it is deleting a variable that doesn't exist.

If the previous loop had back references, then subsequent loops without back references use the wrong value of nlen. The value is larger, meaning that the string terminator from nbuf is copied along to the main buffer, thus terminating the string prematurely. This leads to the final result being truncated, e.g. missing the last (unmatched) part of the string. So "match match tail" become "replaced replaced" instead of "replaced replaced tail". Fix this by resetting nlen to the correct value each time around the lop. Fixes: 855f18ea0e6 ("setexpr: add regex substring matching and substitution") Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | When rebasing this series I had to renumber all my log tests because someone made another log test in the meantime. This involved updaing a number in several places (C and python), and it wasn't checked by the compiler. So I though "how hard could it be to just rewrite in C?" And though it wasn't hard, it *was* tedious. Tests are numbered the same as before to allow for easier review. A note that if a test fails, everything after it will probably also fail. This is because that test won't clean up its filters. There's no easy way to do the cleanup, except perhaps removing all filters in a wrapper function.
