Undefined behavior when the value is negative. Two callers: * gdb_chr_receive() passes an uint8_t value. Safe. * gdb_handlesig() a char value. Unsafe. Not a security issue, because the characters come from the gdb client, which is trusted. The obvious fix would be casting @ch to unsigned char. But note that gdb_read_byte() already casts @ch to uint8_t in many places. Uses of @ch without such a cast: (1) Compare to a character constant with == or != (2) s->linesum += ch (3) Store ch or ch ^ 0x20 into s->line_buf[] (4) Check for invalid RLE count: ch < ' ' || ch == '#' || ch == '$' || ch > 126 (5) Pass to isxdigit() (6) Pass to fromhex() Change the parameter type from int to uint8_t, and drop the now redundant casts. Affects the above uses as follows: (1) No change: the character constants are all non-negative. (2) Effectively no change: we only ever use s->linesum & 0xff, and s->linesum is int. (3) No change: s->line_buf[] is char[]. (4) No change. (5) Avoid undefined behavior. (6) No change: only reached when isxdigit(ch) Signed-off-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20190514180311.16028-5-armbru@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "Debugging with GDB / Appendix E GDB Remote Serial Protocol / Overview" specifies "The printable characters '#' and '$' or with a numeric value greater than 126 must not be used." gdb_read_byte() only rejects values < 32. This is wrong. Impact depends on the caller: * gdb_handlesig() passes a char. Incorrectly accepts '#', '$' and '\127'. * gdb_chr_receive() passes an uint8_t. Additionally accepts characters with the most-significant bit set. Correct the validity check to match the specification.

Not a security issue, because the characters come from trusted $prefix/etc/qemu/bridge.conf and the files it includes. Furthermore, isspace()'s locale-dependence means qemu-bridge-helper uses the user's locale for parsing $prefix/etc/bridge.conf. Feels wrong. Use g_ascii_isspace() instead.

| | | | | | | | | | | | | | | | | | | | | | 8561 and 8562 will be gen15 machines. There is no name yet, let us use gen15a and gen15b as base name. Later on we can provide aliases with the proper name.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | add several new features (msa9, sort, deflate, additional vector instructions, new general purpose instructions) to generation 15. Also disable csske and bpb from the default and base models >=15. This will allow to migrate gen15 machines to future machines that do not have these features.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Let's return the cc value directly via cpu_env. Unfortunately there isn't a simple way to calculate the value lazily - one would have to calculate and store e.g. the population count of the mask and the result so it can be evaluated in a cc helper. But as VTM only sets the cc, we can assume the value will be needed soon either way. Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: David Hildenbrand <david@redhat.com>
