* od_bloaty: fix floating point outputRon Yorston2017-07-192-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently od_bloaty does this: $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -f od: invalid character 'F' in type string 'fF' $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -t fD od: invalid character 'D' in type string 'fD' $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | busybox od -t f 0000000 0000010 The first two occur because the alphabetic length specifier isn't being properly skipped. The third is due to the empty length specifier being treated as alphabetic so we fall off the end of the FDL_sizeof array with undetermined consequences. Coreutils defaults to printing a double in this case. With this patch the output is: $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -f 0000000 0.0000000e+00 0.0000000e+00 0000010 $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -t fD 0000000 0.000000000000000e+00 0000010 $ /bin/echo -en '\x00\x00\x00\x00\x00\x00\x00\x00' | ./busybox od -t f 0000000 0.000000000000000e+00 0000010 I guess nobody uses BusyBox od to print floating point numbers.

* printf: fix format string sanity checkRon Yorston2017-07-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the tests for printf checks for an invalid bare '%' in the format string: $ busybox printf '%' a b c printf: %: invalid format On x86_64 a slightly different test doesn't work correctly: $ busybox printf '%' d e f printf: invalid number 'd' printf: invalid number 'e' printf: invalid number 'f' On other platforms the test fails randomly depending on how the arguments are laid out in memory. There are two places in the code where strchr is used to determine if a character in the format string is valid. However, strchr also returns a valid pointer if the character being searched for is the null terminator thus causing the code to incorrectly suppose that a valid character has been found. Add explicit checks for the null terminator. Signed-off-by: Ron Yorston <rmy@pobox.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
