What does it mean if the write() system call in Solaris returns EACCES?

We're having a weird issue in one of our Bamboo plans, which we can't replicate 'locally' (on the same machine, with the same user)

It's failing to copy a file. Here's a truss log:

The previous command cp -f TestEnvironment.zip /mnt/builds/SEN/Touchstone/Maintenance/10.1/Solaris_sparc_gcc/ succeeds as well.

-bash-3.2$ uname -a
SunOS b2s-sol10spr-4 5.10 Generic_147440-01 sun4v sparc sun4v

So, I went to https://docs.oracle.com/cd/E26502_01/html/E29032/write-2.html, and it doesn't mention EACCES...

What's going on?

Is the destination directory on NFS? Any unusual permission bits or ACLs on /mnt/builds/SEN/Touchstone/Maintenance/10.1/solaris10sparc/gcc4_9 ?
– Mark Plotnick

That directory has 777 permissions (dunno much about acl's.

And that directory is on nfs

Does cat TestEnvironment.zip > /mnt/builds/SEN/Touchstone/Maintenance/10.1/solaris10sparc/gcc4_9/TestEnvironment.zip succeed?
– Mark Plotnick
Dec 15 at 6:27

File locking? I'd try capturing the NFS traffic and seeing what's going on on the NFS server. After 12 successful 8 MB writes to file descriptor 4, you get an EACCESS error from that same file descriptor. That's really strange, as the only way to get that from the local kernel via from the Solaris source posted to the internet is the write() syscall checking for a file lock via the internal nbl_conflict() function.

We're having a weird issue in one of our Bamboo plans, which we can't replicate 'locally' (on the same machine, with the same user)

The previous command cp -f TestEnvironment.zip /mnt/builds/SEN/Touchstone/Maintenance/10.1/Solaris_sparc_gcc/ succeeds as well.

-bash-3.2$ uname -a

So, I went to https://docs.oracle.com/cd/E26502_01/html/E29032/write-2.html, and it doesn't mention EACCES...

What's going on?

Is the destination directory on NFS? Any unusual permission bits or ACLs on /mnt/builds/SEN/Touchstone/Maintenance/10.1/solaris10sparc/gcc4_9 ?

That directory has 777 permissions (dunno much about acl's.

And that directory is on nfs

Does cat TestEnvironment.zip > /mnt/builds/SEN/Touchstone/Maintenance/10.1/solaris10sparc/gcc4_9/TestEnvironment.zip succeed?
– Mark Plotnick

File locking? I'd try capturing the NFS traffic and seeing what's going on on the NFS server. After 12 successful 8 MB writes to file descriptor 4, you get an EACCESS error from that same file descriptor. That's really strange, as the only way to get that from the local kernel via from the Solaris source posted to the internet is the write() syscall checking for a file lock via the internal nbl_conflict() function.

We're having a weird issue in one of our Bamboo plans, which we can't replicate 'locally' (on the same machine, with the same user)

It's failing to copy a file. Here's a truss log:

The previous command cp -f TestEnvironment.zip /mnt/builds/SEN/Touchstone/Maintenance/10.1/Solaris_sparc_gcc/ succeeds as well.

-bash-3.2$ uname -a

So, I went to https://docs.oracle.com/cd/E26502_01/html/E29032/write-2.html, and it doesn't mention EACCES...

What's going on?

We're having a weird issue in one of our Bamboo plans, which we can't replicate 'locally' (on the same machine, with the same user)

It's failing to copy a file. Here's a truss log:

File locking? I'd try capturing the NFS traffic and seeing what's going on on the NFS server. After 12 successful 8 MB writes to file descriptor 4, you get an EACCESS error from that same file descriptor. That's really strange, as the only way to get that from the local kernel via from the Solaris source posted to the internet is the write() syscall checking for a file lock via the internal nbl_conflict() function.

You did not send your sourcecode, but it seems that you call mmap() to get the data you like to write.

I guess that you mapped a region of a file that grants no read access to you.

In order to verify that the problem is not caused by a side effect with mmap() you should call

dd if=filename of=/dev/null

to check whether the problem exists when you definitely only read from the source file.

Then you could have a look at the OpenSolaris sources and look for related EACCESS returns. ACLs are e.g. such a case where a file access could cause EACCESS.

ACLs are e.g. such a case where a file access could cause EACCESS. I'm pretty sure the only way ACLs can cause an EACCESS return is on open() or openat(), although I haven't examined the kernel source. There's no way I can see for ACLs to cause a write() to return EACCESS, especially after a series of successful write() calls on that same file descriptor. Barring something on the NFS server (quite possible, and that's still a complete unknown...), the only way I see in the OpenSolaris source for write() to fail on EACCESS is for it to run into a file lock.

Then you could have a look at the OpenSolaris sources and look for related EACCESS returns. ACLs are e.g. such a case where a file access could cause EACCESS.

ACLs are e.g. such a case where a file access could cause EACCESS. I'm pretty sure the only way ACLs can cause an EACCESS return is on open() or openat(), although I haven't examined the kernel source. There's no way I can see for ACLs to cause a write() to return EACCESS, especially after a series of successful write() calls on that same file descriptor. Barring something on the NFS server (quite possible, and that's still a complete unknown...), the only way I see in the OpenSolaris source for write() to fail on EACCESS is for it to run into a file lock.
