Please get your facts correct. Google does not whine about GPLv3. Google ships GPLv3 licensed code. Google doesn't allow AGPL code, but that is a different license. Apple, however, will not ship GPLv3 code.

On the contrary. Unsolved heinous crimes are still common. Here is one that disturbs me greatly. It is still unsolved to this day. https://www.sfchronicle.com/crime/article/Oakland-Chinese-Ch...

This code doesn't work and has security holes via race conditions. You cannot walk a path using lstat and readlink. Once you have walked past a component you have checked, an attacker can change it to point elsewhere. You must use open

Lord of Light by Roger Zelazny. Something about this book speaks to me. It's a wonderful examination of how the human condition never changes in a world of magic, wonders and terrors beyond imagination.

Of course the irritating thing is that all of their consumer devices are internally Linux as well, including the FireTV's that happily stream Amazon Prime in 4K. So it isn't like they can't do it, just won't.

We just (a week or so ago) added the ability to remove it. You can now configure samba with: --without-smb1-server and the SMB1 code is no longer compiled into the binary :-).

SMB3 is secure over the internet. But you really have to make sure it is an encrypted connection. In Samba you do this by adding: server min protocol = SMB3 smb encrypt = required to the [global] section of your smb.conf.

Not true. mmap is commonly used in malloc implementations. Look at this man page for jemalloc. http://jemalloc.net/jemalloc.3.html "Traditionally, allocators have used sbrk(2) to obtain memory, which is suboptimal for

No, it doesn't. malloc(0) != malloc(0) because the internal malloc header is different for each allocation. Asking for a malloc of size n, means internally the malloc library allocates n + h, where h is the internal malloc header size.

It's just a warmup. Tells me how the candidate thinks about such things. In production code of course the max size is limited to avoid DoS. My bug in Samba was missing the behavior of the zero case.

Well yes. I'm looking for competent C coders. Competent C coders know how malloc works. It goes with the territory.

Many protocols read values of a network to specify how much is left in the packet (it's how packet boundaries are usually encoded, specifically in SMB1/2/3). So yes, no matter how paranoid you are you're eventually going

See the replies below. Someone just submitted a really comprehensive answer !

That's right ! Great answer. malloc() is a very old API. A more modern version would probably looks like: err_code malloc(size_t size, void **returned_ptr); The current malloc() overloads the return to say NULL == no memory available&#

I don't code to in C++ anymore. Did a long time ago. I'm looking for careful programmers around security and API design. This is nothing to do with performance tuning. It's to do with security.

mmap, brk, sbrk are standard POSIX system calls.

by jra_samba 4y ago
It uses the mmap, sbrk or brk system calls. All perfectly callable from C.

Of course malloc is implemented in C. Look at the glibc source code.
