self inserts are great. some people have one they use for every media and i love seeing this one specific little guy people choose to represent themselves go on fun adventures and make friends with their favorite characters and fall in love with others. some people have a different insert for every media they ship from or even for every ship they have and that's??? honestly really impressive and cool how so many different things can represent a single person. sometimes they're fantastical and magical and sometimes they're just A Guy™ in Situations™ even if it doesn't really "fit" the media they're an insert for. and some of these designs?? SNAPPED my spine stole my bones yall are so talented

why do i always feel sick😭

can we kill this guy

Will be f/oposting for all those here who don't know who they are :3

Looking at how `curl` works through stack traces

It's the end of the week! Woohoo! I'm very excited for the weekend. It's the only time I have these days to get lots of coding done on Zarf.

The first couple of relevant lines in the stack trace are pretty self-explanatory. They capture writing the command to standard input (which is defined through file descriptor 2). The one call that intrigued me was the pselect6 call, primarily because I haven't encountered it before. As it turns out pselect6 is responsible for determining whether a file descriptor in a set of file descriptors is ready for interactions. The first two commands are the number of file descriptors to observe and the second is the set of file descriptors to observe. In this case, pselect is only observing the state of file descriptor 0. File descriptor 0 is the standard input file descriptor, so I'm assuming that this system call does something to the effect of checking to see if a user isn't actively typing a command.

write(2, "curl https://safia.rocks", 24) = 24 pselect6(1, [0], NULL, NULL, NULL, {[], 8}) = 1 (in [0]) read(0, "\r", 1) = 1 write(2, "\n", 1) = 1

The next couple of lines in the stack trace invoke a command that I'm familiar with using a rather interesting set of parameters. As mentioned in other blog posts, ioctl is a command that is

ioctl(0, TCGETS, {B38400 opost isig -icanon -echo ...}) = 0 ioctl(0, SNDCTL_TMR_STOP or TCSETSW, {B38400 opost isig icanon echo ...}) = 0 ioctl(0, TCGETS, {B38400 opost isig icanon echo ...}) = 0

The next few lines were variations of this. I've never encountered the rt_sigaction

rt_sigaction(SIGINT, {sa_handler=0x467410, sa_mask=[], sa_flags=SA_RESTORER, sa_restorer=0x7f 3750fe6060}, {sa_handler=0x4bb540, sa_mask=[], sa_flags=SA_RESTORER, sa_restorer=0x7f3750fe60 60}, 8) = 0

The next couple of lines in the stack trace made me realize that I had not configured strace properly before running my curl command. In the stack trace below, there is a call made to the clone syscall which creates a new process thread. Shortly after this new thread is created, the stack trace ends. This made me realize that a lot of the networking-related work must have been happening in that thread. In particular, I was looking to find system calls associated with opening sockets and recving messages from them.

pipe([3, 4]) = 0 clone(child_stack=NULL, flags=CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD, child_tidptr=0 x7f375199ae10) = 13439 = 0

I went back and reran the strace command with the appropriate flag, the f flag, which tells strace to follow child processes and threads. When I did this, I got a stack trace that was much longer and had a lot of the system calls that I expected to see. One of the first networking-related things that happen is related to configurations. In this case, it loads up the default configuration that a user might have set for curl.

[pid 13601] open("/usr/lib/ssl/openssl.cnf", O_RDONLY) = 3 ... [pid 13601] open("/home/safia/.curlrc", O_RDONLY)

As I scrolled through the rest of the stack trace, I realized that it was the kind of thing that should be analyzed in multiple series. Considering the amount of time I have to write these days, I have to keep my blog posts really short. I don't mind this too much. In this case, it'll allow me to parse out this rather hefty stack trace without losing it.

So stay tuned for that!

live cater reaction

i put it in tags but i wanna actually post it:

self shipping is all about having fun!! yumejoshing is fun because of your dynamic with your f/os, not despite it. yk how some people like canon/canon or canon & canon pairings for the dynamic? that's what we do but the other canon character is our s/i. so like,, who cares if you realistically wouldn't get along with them irl? last i checked, this isn't reality, so why act like it is? go absolutely bonkers with your faves it's therapeutic

getting comfy

still thinking about how naru calls nyanko her baby. . .
