2017-04-21yacc: Fix a bug from at least 1995.Dan Cross1-1/+2
Fix a bug folding newlines in strings constants in C code snippets in YACC. This code has existed since at least 2nd Edition Plan 9.

2017-04-08libdraw: replace hand-rolled realloc, preventing buffer overflow.Ray Lai1-3/+1
The original buffer is f->nsubf*sizeof *subf bytes (oldsize) large. Once it's full, a new buffer of (f->nsubf+DSUBF)*sizeof *subf (newsize) is mallocated. Unfortunately memmove() reads (newsize) bytes from the original (oldsize) buffer, causing a buffer overflow. By switching to realloc(), we don't need to do buffer size calculation, memmoving, and freeing of the original buffer.

2017-04-089term: Add missing parentheses, preventing buffer overflow.Ray Lai1-1/+1
(el-sr) is the string length and (sizeof wdir - strlen(name) - 20) is the buffer size. When the string length is greater than the buffer size, the beginning of the string is supposed to be trimmed to fit in the buffer size. Unfortunately a pair of parentheses were missing, pointing sr outside the buffer, and the for loop below then reads outside the buffer. For certain binary data printed in a window, it causes a segfault.

2017-01-09cmd/9term: A hack because I'm constantly getting confused about ^C vs fn+deleteDave Presotto3-0/+11
Since Google (and a lot of the outside) is so engrained with using ^C as interrupt, I'd like to be able to use it in 9term if I've stty'd my intr to ^C. Without this, hitting ^C still works but if the program behind the window isn't reading from /dev/cons, it won't take effect till after I hit a newline which is often very confusing. I know this is a hack since it only works if I stty intr ^C but that seems the only other character that gets used anyways.

2014-06-03acme: fix bufread crash due to typing-point scrollingRuss Cox1-0/+4
Acme tracks the most recent typing insertion point and the home and end keys stop there on their way up to the top or down to the bottom of the file. That point should be iq1, and it should be adjusted properly so that it's always between 0 and t->file->b.nc inclusive. (This is all code from an external contributor, years old at this point but new since Plan 9.) Somehow, sometimes iq1 ends up a little beyond b.nc, and when passed to textbacknl it crashes acme in bufread. I can't see how that can happen but if it does, avoid the crash. It's tempting to pull the insertion point code out entirely but this is a little less invasive and should fix things for now. TBR=rsc https://codereview.appspot.com/107730043
