Re: [9fans] FP register usage in Plan9 assembler

Thanks for the explainations! I did read in the Pike's paper about the syntax name+offset(FP), but I did understood that name had to be a symbol already defined, and I was looking for it in the c code. Sorry for the noise! This led me to another question, however: I've read before that the plan9

[9fans] startboot signature

Out of curiosity, why the startboot function in port/initcode.c is `void startboot(char *argv0, char **argv)` given the argv0 is ignored? I see that this simplify various main() in init9.s but I wonder why not simply use `void startboot(char **argv)` Giacomo

[9fans] Libc locks documentation

Hi, I'm a bit ignorant but I cannot recognise the algorithms in qlock.c. Where I can find more documentation about them? Any paper I can read? For example the rsleep/rwakeup always look a bit magic in its coupling with qlocks. I'd really like to know more about these algorithms, but given their

Re: [9fans] The Plan 9/"right" way to do Facebook

While funny in it's visionary shape, I'm seriously scared about this matter. Take for example Google's material design: any software that successfully mimic the physical world (paper layers in particular) is going to bland our perception of its "virtuality". Our mind is going to accept it as a

Re: [9fans] memory leaks in libmp

Oh, well, I'm sorry, I should have clarified the context a bit more. Here it is. The link I provided here are Jehanne issues, not Plan 9 or 9front bug reports. After fixing a few of them I realized that, an year from now, I won't be able to remember why I did the change. Also, coverity could shut

[9fans] out of bound access in libsec

Hi, running coverity scan on libsec it reported two defects that do not seem false positives: 1. an out of bound access to aesXCBCmac (see https://github.com/JehanneOS/jehanne/issues/3 ) 2. an out of bound access in msgRecv, tlshand.c:1809 (see https://github.com/JehanneOS/jehanne/issues/4 ) I

Hi, these other two defects identified from Coverity scan that you might find interesting: https://github.com/JehanneOS/jehanne/issues/5 https://github.com/JehanneOS/jehanne/issues/6 NOTE: 9front's guys consider these a false positive, since both mptole(n, nil, 0, nil); and mptobe(n,

[9fans] Why getenv replaces \0 with spaces in the returned value?

Hi, last night I noticed this strange post processing in 4th edition's getenv: https://github.com/brho/plan9/blob/master/sys/src/libc/9sys/getenv.c#L34-L41 seek(f, 0, 0); r = read(f, ans, s); if(r >= 0) { ep = ans + s - 1; for(p = ans; p < ep; p++)

[9fans] devsegment usage examples

Hi, I'm looking for an usage example of devsegment. I cannot find anything neither in bhro's plan9 nor in 9front. Can anybody share a real usage world example? Giacomo

Re: [9fans] devsegment usage examples

Neat, thanks! I wonder if a similar approach could be used to move some device drivers out of kernel... Btw, I did read the sample in segment(3) but I was looking for a real world example. What I'm trying to understand is not *how* to use devsegment, but *when* to use it. Which problems is it
